Detailed Description
In order to make the technical problems solved, technical solutions adopted and technical effects achieved by the present invention clearer, the technical solutions of the embodiments of the present invention will be described in further detail below with reference to the accompanying drawings, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
Example one
Fig. 1 is a block diagram of a banknote box according to an embodiment of the present invention. The cassette can be integrated in a cassette system. As shown in fig. 1, the banknote cassette 100 includes: electronic switch 110, encryption chip 120 and control circuit board 130.
The electronic switch 110 is arranged on the cash box and used for detecting the opening and closing state of a box door of the cash box; the encryption chip 120 is electrically connected with the electronic switch 110 and is used for encrypting and storing the historical opening and closing records of the box door according to the opening and closing states; and the control circuit board 130 is arranged inside the cash box, is electrically connected with the encryption chip 120, and is used for controlling the current working state of the cash box according to the history switch record.
Various symmetric and asymmetric algorithms can be integrated in the encryption chip, the encryption chip has extremely high security level, and keys and information data stored in the encryption chip can not be illegally read and tampered.
Illustratively, the encryption chip in the present embodiment is disposed on the control circuit board and electrically connected to the electronic switch. When the cash box is transported, as long as the electronic switch detects that the cash box door is opened, the encryption chip can store the action of opening the cash box door, and even if the cash box door is closed again, the opening record (which can comprise the opening time) of the cash box door can be always stored by the encryption chip. Therefore, the use of the encryption chip endows the cash box with intelligent performance, and the opening and closing state of the cash box can be monitored in real time.
For example, when the banknote box is transported, if the electronic switch detects that the banknote box door is opened, the encryption chip will trigger the functional circuit in the control circuit board, for example, the functional circuit may be controlled to be locked, so that the functional circuit cannot normally operate, and the banknote box is further controlled not to be started, so as to ensure the security of the banknote box.
Further, an embodiment of the present invention further provides a financial self-service device, and when the financial self-service device detects that the banknote box provided in any embodiment of the present invention is installed in the financial self-service device, the financial self-service device decrypts a history switch record stored in a banknote box encryption chip. Judging whether the box door is opened or not according to the history switch record; if the door is judged to be opened once, the cash box is not started.
Illustratively, for the historical switch record stored in the encryption chip in an encrypted manner, if the historical switch record is stored in the encryption chip in an encrypted manner, when the banknote box is placed in the financial self-service device, the banknote box will be decrypted in the financial self-service device to obtain the historical switch record.
The history switch record may also be stored in a non-volatile Memory of the banknote cassette, such as a Flash Memory (Flash) or an Electrically Erasable Programmable Read-Only Memory (EEPROM), for example. If the historical switch records are stored in the memory, the financial self-service equipment can directly read the historical switch records of the box door when the cash box is installed in the financial self-service equipment.
For example, no matter where the history switch record is stored, as long as the processor of the financial self-service device reads the history switch record that the door of the cash box has been opened, it indicates that there is a safety hazard in the cash box, and if the cash box continues to be used, it may cause a situation that the actual account is not unified with the expected account of the system, so the financial self-service device does not start the cash box. The financial self-service equipment can be equipment capable of performing financial transactions, such as an automatic deposit machine, an automatic teller machine or a cash sorter.
The embodiment of the invention provides a money box which comprises a control circuit board, an electronic switch and an encryption chip. By adopting the technical scheme provided by the embodiment of the invention, the opening record of the box door is always stored by the encryption chip in the process of transporting and maintaining the cash box. If the electronic switch detects that the door of the cash box is opened, the encryption chip immediately stores the opening and closing record of the door of the cash box and simultaneously triggers a functional circuit in the control circuit board so as to control the current working state of the cash box. If the encryption chip is not allowed, the functional circuit in the control circuit board cannot work normally. When the money box is installed in the financial self-service equipment, the financial self-service equipment can read the historical opening and closing record of the door of the money box from the encryption chip, judge whether the door of the money box is opened or not according to the opening record, and further determine whether the money box is started or not, so that the safety of the money box in the circulation process is guaranteed.
Example two
Fig. 2a is a block diagram of a banknote cassette management system according to a second embodiment of the present invention. As shown in fig. 2a, the cash cassette system 200 includes a base 210, a financial self-service device 220 and a cash cassette 230 provided in the above embodiments.
When the banknote box 230 is detached from the financial self-service device 220 and placed on the base 210, the banknote box 230 is encrypted through the base 210 to obtain an encrypted banknote box; wherein, the base is one of the encrypting devices which can encrypt the money box. The encryption device can directly encrypt the cash box, and can also indirectly encrypt the cash box under the control of the cash adding center.
When the encrypted banknote box is installed in the financial self-service device 220, the financial self-service device 220 decrypts the encrypted banknote box to obtain decryption information, verifies the decryption information, and judges whether to start the banknote box according to a verification result. (the state represented by this process is shown in FIG. 2 b). For example, the financial self-service device in the present embodiment may be any financial self-service device provided in the above embodiments.
It should be noted that, when the banknote cassette is placed on the base, the banknote cassette may be authenticated before the base encrypts the banknote cassette. For example, the authentication of the cassette may preferably be a legitimacy authentication of the cassette. For example, it is possible to determine whether the cassette is produced by a normal cassette producing company, whether the circulation thereof is permitted by a financial institution, and the like by recognizing the cassette identification. The banknote box identifier can be a bar code assigned to the banknote box by a production company of the banknote box or an ID number assigned to the banknote box by a financial institution before the banknote box leaves a factory. Illustratively, when the validity of the banknote box is authenticated, the base can upload the identification information to the banknote adding center, the banknote adding center can match the identification information of the banknote box stored in the database in advance after acquiring the information, and if the matching is successful, the banknote box is determined to be authenticated successfully. After the cash box is confirmed to be successfully authenticated, the base can write the signature information into the cash box. The signature information may include a serial number of the cash box, a barcode, and the like.
For example, after the banknote cassette is authenticated and the signature information is written in, the banknote cassette can be encrypted. Exemplarily, the step of encrypting the banknote box through the base specifically includes: and writing the signature information and the encryption information into an encryption chip of a cash box for encryption according to a preset encryption rule, wherein the encryption information comprises the cash adding amount of the cash box and a preset private key. Fig. 2a shows the banknote cassette when placed on the base, and the banknote cassette is authenticated, signed information is written, and encrypted by the base.
It should be further noted that after the encryption operation is completed, the original switch record stored in the banknote box encryption chip needs to be cleared, so as to ensure the validity of the historical switch record read by the subsequent financial self-service device.
Illustratively, the preset encryption rule is preferably an asymmetric encryption algorithm. The algorithm is a secret method of a secret key, and the safety is very high. The preset asymmetric algorithm generally requires two keys: namely a public key (publickey) and a private key (privatekey). The public key and the private key are a pair of keys, and if the public key is used for encrypting data according to the preset asymmetric algorithm, the data can be decrypted only by using the corresponding private key and based on the preset asymmetric algorithm. Similarly, if data is encrypted with a private key, it can only be decrypted with the corresponding public key. In the technical scheme provided by this embodiment, the preset private key can be written into the encryption chip through the base, and the banknote box is encrypted to obtain the encrypted banknote box. And the preset public key corresponding to the preset private key can be sent to the financial self-service device corresponding to the encrypted money box through the money adding center, so that the financial self-service device decrypts the encrypted money box according to the preset public key.
For example, since the preset public key and the preset private key have a corresponding relationship, if the preset private key is written into the banknote box, the encrypted banknote box can be decrypted only through the preset public key, and then the encrypted banknote box can be started. Therefore, in the process of transportation and maintenance of the encrypted money box, due to the existence of the preset private key, lawless persons cannot open the money box at will to steal cash, even if the encrypted money box is manually exchanged in the process of transportation or maintenance, the encrypted money box cannot be normally started, and the safety of the money box is effectively guaranteed.
Fig. 2b is a block diagram of a banknote cassette management system according to a second embodiment of the present invention, and fig. 2b shows a state in which the financial self-service device decrypts a banknote cassette and verifies decryption information when the banknote cassette is placed in the financial self-service device. If the banknote box placed in the financial self-service device shown in 2b is an encrypted banknote box which is already encrypted, at this time, if a preset public key corresponding to a preset private key in the encrypted banknote box is not stored in the financial self-service device, the encrypted banknote box still cannot be started. The phenomenon that the cash box is imitated is avoided to a certain extent, and the safety and the reliability of the financial self-service device during operation are further improved.
Preferably, when the encrypted banknote box is placed in the financial self-service device, the financial self-service device is specifically configured to: decrypting the encrypted banknote box by using a preset public key corresponding to a preset private key to obtain decryption information; acquiring signature information from the decryption information; verifying the signature information; if the signature information is verified successfully, acquiring a history switch record; judging whether the box door is opened or not according to the history switch record; if the cassette door was opened, the cassette is not activated.
Illustratively, when the encrypted banknote box is placed into the financial self-service device, the financial self-service device decrypts the banknote box to obtain decryption information, and then obtains the historical switch record, and if the historical switch record does not have the record that the door of the banknote box is opened, the signature information is verified, and then whether the banknote box is started or not is determined. Illustratively, the cassette is not activated if the signature information verification is unsuccessful.
For example, the self-service financial device may verify the signature information by: and acquiring the serial number and the bar code of the cash box from the signature information, respectively matching the acquired serial number and the bar code with the serial number and the bar code which are prestored in the financial equipment (or acquired from a cash adding center), and if the serial number and the bar code are matched successfully, indicating that the signature information is verified successfully. And if one of the two fails to be matched or both fail to be matched, the signature information is indicated to fail to be verified. And under the condition that the signature information verification fails, the financial self-service device does not start the cash box.
For example, if the history switch record is stored in the nonvolatile storage of the cash box but not in the encryption chip, in this case, when the encryption cash box is placed into the financial self-service device, the financial self-service device may also read the history switch record of the cash box first, and determine whether the door of the cash box has been opened according to the history switch record; if the door of the cash dispenser box is judged to be opened, the cash dispenser box is not started. And if the financial self-service device judges that the door of the cash dispenser box is not opened, the cash dispenser box is decrypted to obtain decryption information. And acquiring signature information from the decryption information, verifying the signature information and further judging whether to start the cash box.
For example, when the encrypted banknote box is placed in the financial self-service device, the banknote box can be started only when the signature information is verified to pass and the financial self-service device judges that the door of the banknote box is not opened.
Further, the encryption system can also comprise a prompting device which is connected with the financial self-service device and used for uploading the verification result of the decryption information to a control center of the financial self-service device so as to inform the control center of the current use condition of the cash box.
Specifically, when the banknote box is subjected to validity verification failure by the financial self-service device, the result of the validity verification failure is uploaded to the control center of the financial self-service device through the prompting device, so that the control center can know the potential safety hazard of the banknote box and perform safety verification to eliminate the potential safety hazard.
The embodiment provides a banknote box system, which comprises a base, a financial self-service device such as an automatic deposit machine or an automatic teller machine and the like, and a banknote box provided by the embodiment. When the money box is detached from the financial self-service device and placed on the base, the money box can be encrypted through the base to obtain the encrypted money box. The preset private key can be written into the encryption chip of the cash box, so that the financial self-service device can decrypt the encrypted cash box only by using the preset public key corresponding to the preset private key, and further can further judge whether to start the encrypted cash box, so that the condition that the cash box is illegally opened or replaced in the transportation and maintenance processes is avoided, and the safety of funds in the cash box is guaranteed. When the encrypted banknote box is placed into the financial self-service device, the financial self-service device needs to decrypt the encrypted banknote box to obtain decryption information, and whether the banknote box is started or not is judged after signature information and history switch records in the decryption information are verified respectively. By adopting the technical scheme, the safety of the money box is improved, and meanwhile, the illegal money box is prevented from being circulated to a financial system.
It is to be noted that the foregoing is only illustrative of the preferred embodiments of the present invention and the technical principles employed. It will be understood by those skilled in the art that the present invention is not limited to the particular embodiments described herein, but is capable of various obvious changes, rearrangements and substitutions as will now become apparent to those skilled in the art without departing from the scope of the invention.
