Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are some, not all, embodiments of the present invention. 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.
In the embodiments of the present invention, words such as "exemplary" or "for example" are used to mean serving as examples, illustrations or descriptions. Any embodiment or design described as "exemplary" or "e.g.," an embodiment of the present invention is not necessarily to be construed as preferred or advantageous over other embodiments or designs. Rather, use of the word "exemplary" or "such as" is intended to present concepts related in a concrete fashion.
The terminal provided by the embodiment of the invention can be a Mobile phone, a tablet Computer, a notebook Computer, an Ultra-Mobile Personal Computer (UMPC), a netbook, a Wearable Device, a vehicle-mounted Device or a Personal Digital Assistant (PDA), and the like. It should be noted that the specific type of the terminal is not limited in the embodiment of the present invention. In the embodiment of the present invention, LTE and NR systems are taken as examples, but the present invention is not limited to this system, and the technical solution provided by the present invention may be applied to other systems having the same problem.
As shown in fig. 1, an embodiment of the present invention provides an information encryption method, applied to a first terminal, including:
Wherein the first input is a sliding operation or a tapping operation.
And 102, responding to the first input, acquiring input information of the first input, and encrypting the input information by using fingerprint information corresponding to the first input.
In this step, the first input information is the information to be transmitted of the first terminal, in other words, the fingerprint information corresponding to the first input is used for encrypting the information to be transmitted; specifically, the system may encrypt while inputting.
And 104, responding to the second input, sending the input information, and encrypting to obtain encrypted information.
According to the scheme provided by the embodiment of the invention, during group chat, the authority management such as encryption and decryption is carried out through the fingerprint information, the operation is simple, the compatibility is strong, and other special dependence is not required.
As shown in fig. 2, a user inputs information by tapping or sliding a keyboard with a finger in a keyboard area, and the first terminal detects fingerprint information at the same time and records and retains the current first input fingerprint information; and the fingerprint information corresponding to the first input is used for encrypting the input information of the first input to obtain encrypted information. On the group chat interface of the first terminal side, the encrypted information sent by the first terminal side can be displayed in plain text (i.e. directly displaying the first input information) or in cipher text (i.e. displaying the encrypted information of the first input information); on the other member's interface, the information sent by the first terminal is displayed by the cipher text (i.e. the encrypted information of the first input information is displayed).
Optionally, in the above embodiment of the present invention, before step 101, the method further includes:
receiving a third input;
in response to the third input, an encryption input mode is initiated.
In other words, the user may activate or deactivate the encryption input mode through the encryption input switch of the system.
As an alternative embodiment, the third input comprises:
a preset gesture input acting on the group chat interface; the preset gesture is used for starting or closing encryption input.
For example, as shown in fig. 3, in the group chat interface, when a finger of the user slides inward from an edge of the keyboard area by a preset distance, the encryption input is started or closed; alternatively, as shown in fig. 4, the first terminal may prompt the user whether the current state is to enable or disable the encryption input. After the encryption input is turned on through the preset gesture input, the background color of the input method keyboard area is changed to be gray or other dark colors, the background color of the keyboard area is restored to be the original color after the encryption input is turned off, and fig. 5 is a schematic diagram of the keyboard area with the background changed in the encryption input state.
As another alternative embodiment, the third input comprises:
clicking input of a virtual key acting on the group chat interface; the virtual key is used for starting or closing encryption input.
For example, as shown in fig. 6, a virtual key for starting or closing the encryption input is provided in the keyboard region, and the encryption input function is turned on or closed by clicking the virtual key. Likewise, the first terminal may prompt the user whether the current state is to enable or disable the encryption input. After the encryption input is opened through the virtual keys, the background color of the input method keyboard area is changed into gray or other dark colors, and the background color of the keyboard area is restored to the original color after the encryption input is closed.
Optionally, in the foregoing embodiment of the present invention, the encrypted information is displayed as a processed character string; or, the encrypted information is displayed as a plurality of target symbols; or, the encrypted information is displayed as information subjected to mosaic blurring processing.
For example, as shown in fig. 7, member a (i.e., the first terminal) transmits encrypted information, which is displayed as a processed character string. A specific processing method may be to display the information as XXXX, or to perform mosaic blurring processing or the like.
Further, in the foregoing embodiment of the present invention, before step 103, the method further includes:
receiving a fourth input for selecting at least one group chat member in the group chat member list;
in response to the fourth input, determining that fingerprint information of the group chat member selected by the fourth input has the authority to decrypt the encrypted information.
When the first terminal sends the encrypted information, the first terminal directly selects fingerprints of group chat members which can view the encrypted information; specifically, a specific group chat member is designated through the fourth input, and the fingerprint information of the designated group chat member is endowed with the authority of decrypting the encrypted information by the system. For example, as shown in fig. 8, after clicking the "+" button shown in fig. 8, a list of group chat members shown in fig. 9 pops up, and the user can check the group chat members who can view the piece of encrypted information among the group chat members shown in fig. 9.
Or, the group chat members who can view the piece of encrypted information are determined according to rules predefined by the system.
In summary, in the above embodiments of the present invention, the fingerprint information corresponding to the first input directly encrypts the first input information and then sends the encrypted information, so that the group chat user can perform the fifth input in the display area of the encrypted information, and the fingerprint information corresponding to the fifth input realizes the decryption function, and the operation is simple, the compatibility is strong, and no other special dependence is required.
As shown in fig. 10, an embodiment of the present invention further provides an information decryption method, which is applied to a second terminal, and includes:
In this embodiment of the present invention, the fifth input may specifically be a sliding operation input of a finger of a user, a scraping operation input, or an input of a display area where other fingerprints can be read and act on encrypted information, which is not specifically limited herein.
As shown in fig. 11, the group chat members may scrape the display area where the encrypted information is located by sliding the fingers, and the system detects whether the fingerprint information of the current finger has permission to decrypt and display the current encrypted information; and when detecting that the fingerprint information with the authority is subjected to sliding scraping on the area, displaying the encrypted information.
Optionally, the method further includes:
responding to the fifth input, and if the fingerprint information corresponding to the fifth input does not have the authority of decrypting the encrypted information, displaying prompt information, wherein the prompt information is used for indicating that the current user does not have the authority of viewing the encrypted information.
As shown in fig. 12, when it is detected that the current fingerprint information is not authorized to be decrypted, the user is prompted that the information is not currently authorized to be viewed.
As an alternative embodiment, the method further comprises:
and judging whether the fingerprint information corresponding to the fifth input has the authority of decrypting the encrypted information.
The embodiment of the invention provides various ways for judging whether the current fingerprint information has the authority, which are respectively as follows:
the first method is as follows: the judging whether the fingerprint information corresponding to the fifth input has the authority of decrypting the encrypted information includes:
if the contact information of the opposite side is stored between the user of the fingerprint information corresponding to the fifth input and the user of the fingerprint information used by the encrypted information, determining that the fingerprint information corresponding to the fifth input has the authority of decrypting the encrypted information; otherwise, determining that the fingerprint information corresponding to the fifth input does not have the authority of decrypting the encrypted information. Wherein, the contact means includes: a phone number, a social account number, an instant messenger account number, etc., which are not specifically limited herein.
In other words, whether or not there is an authority is determined based on whether or not the fingerprint information corresponding to the fifth input and the fingerprint information used for the encryption information are contact addresses in which the other party is stored. For example, it may be determined from the relationship of the member A, B, C and the current encryption information producer D. For example, if a and D are related to each other as friends, relatives, or friends, then a is allowed to view the message by fingerprint verification. B. C has no such relationship and therefore the fingerprint information of B, C will not be able to view the encrypted information sent by D.
The second method comprises the following steps: the judging whether the fingerprint information corresponding to the fifth input has the authority of decrypting the encrypted information includes:
if the time for the user who inputs the corresponding fingerprint information to join the current group chat is longer than a preset value, and the time for the user who inputs the corresponding fingerprint information to join the current group chat is longer than the time for the user who uses the fingerprint information used by the encrypted information to join the current group chat, determining that the fingerprint information corresponding to the fifth input has the authority of decrypting the encrypted information; otherwise, determining that the fingerprint information corresponding to the fifth input does not have the authority of decrypting the encrypted information.
In other words, whether or not there is a right can be determined according to the grouping time. For example, member B is in group for a longer time, reaches the threshold K, and is longer than the encryption information input person D, so the fingerprint of B can decrypt the encryption information of the encryption information input person D.
The third method comprises the following steps: the judging whether the fingerprint information corresponding to the fifth input has the authority of decrypting the encrypted information includes:
and if the user of the fifth input corresponding fingerprint information is a group manager of the current group chat, determining that the fingerprint information corresponding to the fifth input has the authority of decrypting the encrypted information.
For example, the member C is a group administrator, so that the fingerprint information of C has super authority, and the encrypted information issued by the encrypted information generator D can be viewed by using the fingerprint information of C as well.
The method is as follows: the judging whether the fingerprint information corresponding to the fifth input has the authority of decrypting the encrypted information includes:
if the fingerprint information corresponding to the fifth input is the fingerprint information of the group chat member selected by the first terminal and having the authority of decrypting the encrypted information, determining that the fingerprint information corresponding to the fifth input has the authority of decrypting the encrypted information; otherwise, determining that the fingerprint information corresponding to the fifth input does not have the authority of decrypting the encrypted information.
In short, when the first terminal sends the encrypted information, the first terminal directly selects which fingerprints of the group chat members can view the encrypted information; specifically, a specific group chat member is designated through the fourth input, and the fingerprint information of the designated group chat member is endowed with the authority of decrypting the encrypted information by the system. Correspondingly, the second terminal determines whether the authority is available according to whether the current fingerprint information is the fingerprint information of the group chat member selected by the first terminal and having the authority to decrypt the encrypted information. For example, if member B is a group chat member selected by the encrypted information inputter D to view the piece of encrypted information, the fingerprint of B may decrypt the encrypted information of the encrypted information inputter D; the fingerprint information of other members cannot decrypt the encrypted information.
In summary, in the above embodiments of the present invention, the fingerprint information corresponding to the first input directly encrypts the first input information and then sends the encrypted information, so that the group chat user can perform the fifth input in the display area of the encrypted information, and the decryption function is realized by the fingerprint information corresponding to the fifth input, so that the operation is simple, the compatibility is strong, and no other special dependence is required; the public information can be directly subjected to reading authority management according to the fingerprint information, the user operation is simple and convenient, and the information safety is effectively improved.

a first receiving module 301, configured to receive a first input acting on the group chat interface;
a first response module 302, configured to, in response to the first input, obtain input information of the first input, and encrypt the input information by using fingerprint information corresponding to the first input;
a second receiving module 303, configured to receive a second input;
