Safety system

Abstract

The invention provides a safety system which comprises a key, a switch device and a processor connected with the switch device, wherein the key comprises a storage unit and a display unit, the storage unit is used for storing decryption picture information used as ciphers, and the display unit is used for displaying the decryption picture information; the processor comprises an image acquiring unit, a data processing unit and a control unit, the image acquiring unit is used for acquiring the decryption picture information displayed by the display unit and transmits the decryption picture information to the data processing unit, and the data processing unit is used for storing cipher picture information and compares the decryption picture information acquired by the image acquiring unit with the cipher picture information stored by the data processing unit. When the decryption picture information is consistent with the cipher picture information, the data processing unit outputs corresponding signals to a control unit for controlling the start of the switch device.

Description

technical field [0001] The invention relates to a security system, in particular to a security system using a picture as a password. Background technique [0002] With the rapid development of science and technology, locks and various locking devices manufactured by adopting various principles are widely used by people. This type of locking device is also a security system. The security system that people generally use mainly contains two kinds at present, and the one, various traditional mechanical locks, the 2nd, various electronic locks. Whether it is a mechanical lock or an electronic lock, using numbers as a password is a common method. The use of numbers as passwords is usually done by sorting or comparing numbers to achieve the effect of secrecy. [0003] However, security systems using numbers as passwords have the following disadvantages: First, the memory of the password is troublesome. If the number of digits is too short, it is easy to be cracked, and if the n...

Problems solved by technology

[0003] However, security systems using numbers as passwords have the following disadvantages: First, the memory of the password is troublesome. If the number of digits is too short, it is easy to be cracked, and if the number of digits is too long, it is easy to forget and cause inconvenience; Single, using only numbers as a password can be easily deciphered

Therefore, its secrecy effect is unsatisfactory; third, it is not convenient to operate by means of a keyboard or a dial pad to input a password
