Abstract (en)
[origin: EP0623722A1] It is disclosed a security device (4,6) for lockin, in a manner that can be opened, generic leaves. The device comprises a hologram (45) wherein informations are recorded and which is formed on a portable support (41,61), an opto-electronic reader of said hologram for comparing said informations with identification informations stored in the reader, and means for locking/unlocking the leaf (1) controlled by the reader. The leaf (1) locking means are operated after the reader has read the hologram (45) and compared the informations recorded thereon with the identification informations stored in the reader itself. Since the parameters used for recording the hologram (45) can be many and widely varying ones, the informations contained therein are the result of a large number of combinations which make them virtually impossible to duplicate and decode. <IMAGE>
