Safe System and Its Key Based on Ultrasonic Imaging and Recognition Technology

Abstract

The invention discloses a safe case system based on an ultrasonic wave imaging and a recognition technology and a key thereof. The safe case system based on the ultrasonic wave imaging and the recognition technology comprises an ultrasonic wave sensing module, an ultrasonogram image processing module, a central system module and a safety lock switch module, wherein the ultrasonogram image processing module can carry out imaging process according to the electrical signal received by the ultrasonic wave sensing module, and an imaging result is transferred to the central system module; the central system module can analyze the imaging information obtained from the imaging module, the imaging information is compared with deblocking image information in internal storage, and if the unblocking requirement is met, and the safety lock switch module sends an unlock signal; and a deblocking code of the key is hidden in the key in a graph or character form. The safe case system provided by the invention combines a computer technology and the ultrasonic wave imaging and the recognition technology, the safe case system has the advantage that the operation and management of the electronic safe case are convenient, the key is not easy to copy and fabricate, and the security is greatly improved.

Description

technical field [0001] The invention relates to the safe technical field of safes, in particular to a safe system based on ultrasonic imaging and identification technology and a key thereof. Background technique [0002] With the rapid development of social economy, people's income increases, and people's social life becomes more and more frequent, the frequency of going out is high, and the time is long. How to ensure the safety of property has become a common concern of people. Safes have become the first choice for people to store valuables and confidential documents. A safe place to rest. Among the more common safes and cabinets on the market, the commonly used passwords are: mechanical, electronic, biometric and so on. [0003] The characteristic of mechanical password safes is that the password adopts an all-mechanical structure, the product performance is very reliable and stable, and the product does not need any maintenance for life, so the cost is low. The disad...

AI Technical Summary

Problems solved by technology

[0010] (1) Mechanical password safes are cumbersome to operate, poor in usability, and have a small amount of passwords

The mechanical password safe has the longest development time, the most mature cracking technology, and poor security

[0011] (2) Electronic password safes have poor anti-interference performance of electronic passwords, and the unlocking passwords are easy to be copied or cracked, posing potential safety hazards

[0012] (3) The dry humidity requirements of fingerprint identification opponents are relatively strict, and it is easy to leave fingerprints on the surface of smooth objects in daily life. There is a possibility that fingerprint traces can be used to copy fingerprints, which are easy to leak or be forged

[0013] (4) Both iris recognition and face recognition have the advantages of high recognition rate, non-contact, and difficulty in counterfeiting, but the recognition algorithm is complicated and the equipment cost is expensive, so it is not suitable for general users
