Embodiment 1

[0048] The invention discloses a password system. The core of the invention is to use the muscle current biosignal of the human arm for user identity authentication and password verification.

[0049]The specific technology of the present invention is implemented as a ring segment design with a scalable shape, which can be worn on the user's wrist or forearm. On the inner side of the ring device close to the skin of the arm, multiple epidermal muscle current sensors are placed according to the main muscle position characteristics of the forearm controlling fingers and wrist. The sensor may, but is not limited to, adopt single-differential or double-differential mode, and the picked-up signal becomes a continuous digital signal flow that can be processed by a signal processor or a central processing unit through corresponding analog signal filtering, amplification, analog signal digital conversion and other circuits, Realize two aspects of processing: gesture recognition proces...

Embodiment 2

[0054] see Figure 4 , the present invention discloses a password system, which includes: a myoelectric sensing terminal 10 , a password setting module 20 , and a password identification module 30 .

[0055] The electromyography sensing terminal 10 is used to collect the muscle current on the skin surface of the user's human body and extract the characteristic value of the electromyography signal. The password setting module 20 is used to generate a password according to the muscle current signal collected by the myoelectric sensing terminal 10 . The password identification module 30 is used to compare and match the muscle current signal collected by the myoelectric sensing terminal 10 with the set password and perform matching analysis to realize user identity verification.

[0056] In this embodiment, the password setting module is used to record and set the user's skin surface muscle current signal, from which the gesture corresponding to the muscle current signal is analy...

Embodiment 3

[0063] The difference between this embodiment and Embodiment 2 is that in this embodiment, the password setting module is used to generate a corresponding password according to the user-specific muscle current signal.

[0064] The password identification module is used to identify the muscle current signal collected by the myoelectric sensing terminal and compare it with the muscle current signal in the set password to determine whether it is consistent or within a certain safety range.

Abstract

The invention discloses a password system and an encryption and decryption method. The password system comprises a muscle current sensing terminal, a password setting module and a password identification module, wherein the muscle current sensing terminal is used for collecting muscle current on the surface of the skin of a human body and extracting a muscle current signal characteristic value; the password setting module is used for generating a password according to a muscle current signal acquired by the muscle current sensing terminal; the password identification module is used for performing comparison and matching analysis on the muscle current sensing terminal acquired by the muscle current sensing terminal and a set password so as to verify the identity of a user. According to the password system provided by the invention, the password is obtained according to the muscle current signal, and the data security can be improved.

Description

technical field [0001] The invention belongs to the technical field of electronic information, and relates to a cryptographic system, in particular to a cryptographic system combined with electromyographic signals; meanwhile, the present invention also relates to an encryption and decryption method. Background technique [0002] In order to improve security, existing electronic devices are usually encrypted by setting a password. However, the security of this method is poor, and the password may be intercepted by a Trojan horse or obtained by others, resulting in leakage of confidential information and property loss. [0003] At the same time, conventional password systems cannot verify biometric features (such as fingerprints and irises), so as long as the password is lost, great losses may be caused. [0004] In view of this, there is an urgent need to design a new cryptographic system to overcome the above-mentioned defects in the existing cryptographic systems. [0005...
