Embodiment Construction

[0023] The present invention will be further explained below in conjunction with the embodiments and drawings

[0024] The working path block diagram of the safety lock based on laser holography of the present invention (as attached figure 1 Shown). It can be seen from the figure that a safety lock based on laser holography of the present invention is characterized in that the user's original PIN code 11 is converted into an original PIN image 12, and the biometric encrypted image 13 generates a biometric encryption key 14, which is encrypted by optical holography. 15 Generate an encrypted hologram 16, store it in the optical holographic recording material, and then embed it in front of the electronic chip of the smart card 17. The user’s biometric decryption image 21 generates a biometric decryption key 22, and passes through the optical holographic decryption path 23. If the key is correct, the correct PIN decryption image 24 is output, and then the correct PIN code is output, ...

Abstract

The invention relates to a security lock based on laser holography, and relates to the technical field of optical image encryption. The security lock, which optically and holographically encrypts users' PIN codes by taking biological feature information as secret keys, is characterized in that the users' original PIN codes are converted into PIN images, biological feature encryption images generate biological feature encryption secret keys, encrypted holograms are generated by optical holographic encryption paths and are stored in optical holographic recording materials, and the optical holographic recording materials are embedded in front of an electronic chip of a smart card; users' biological feature decryption images generate biological feature decryption secret keys to pass through optical holographic decryption paths, correct PIN decryption images are output to acquire the correct PIN codes if the decryption secret keys are correct, and user information is output; a security lockis added at the front end of a memory chip, an optical encryption method is integrated on the basis of original digital encryption of the smart chip card, and accordingly, the information security ofthe smart card is improved.

Description

Technical field [0001] The invention relates to the technical field of optical image encryption, in particular to a safety lock based on laser holography. Background technique [0002] Smart card (smart card) is also called integrated circuit card (IC card), which embeds an integrated circuit chip in a certain material and encapsulates it into a card type. This concept was proposed in the early 1970s. The French company BULL first developed a smart card product in 1976. In 1978, Germany's Siemens (SIEMENS) company produced the world's first chip smart card. After that, smart cards have been widely used in many fields such as finance, medical care, transportation, and identity certification by virtue of their large storage capacity, high reliability and high security, which greatly improved the modernization of people's lives and work. [0003] However, with the gradual expansion of the field of smart card use, various forms of crimes against smart card information attack and theft...
