Logging system and logging method based on multi-combination code

Abstract

The invention discloses a logging system and logging method based on a multi-combination code. The logging system includes a signal generating cell, a coding cell and a memory cell, wherein the signal generating cell successively generates multiple groups of input signals; the coding cell comprises an assignment cell and a transcoding cell, and the assignment cell sets different character values for different input signals; the transcoding cell converts each group of input signals to a group of character sequences, and the group of character sequences is a group of identification codes, namely the coding cell encodes each group of input signals into a group of identifiable codes successively, and each group of identifiable codes serves as a basic code element; the storage cell successively saves multiple groups of identifiable codes, and the basic code elements are combined with one another to form a multi-combination code. The logging system and logging method based on the multi-combination code can greatly increase code space; by adopting implement method of pushing keys or key sleeves, finger-touch information input is achieved, and therefore, more convenience is provided for memorizing codes; moreover, total-blindness input is achieved, and therefore, it is ensured that codes are prevented from being peeped by other people and the safety is high.

Description

technical field [0001] The invention belongs to the technical field of password compilation, and in particular relates to a cataloging system and a cataloging method of multiple combination codes. Background technique [0002] Cryptography technology is widely used in many security fields such as finance, commerce, communication, and life, and plays a very important role in protecting people, property, and privacy. Traditional passwords generally include two types of passwords: characters and graphics. For character passwords, one character is entered at a time, and they are combined in sequence to form a set of passwords. In order to make the password space larger, it is often necessary to set buttons corresponding to more characters, or require a longer password length. Graphical password, draw a group of polylines on the graph, and a group of polylines corresponds to a group of passwords. Although fewer keys can be set, this input method must be equipped with a display. ...

AI Technical Summary

Problems solved by technology

Both character and graphic passwords have the defect of being easy to be peeped, and the password space is small, and it is easy to be cracked by brute force enumeration; although the shape feature password has a large encoding space, this method is not only costly, but also has the characteristics of being difficult to replicate, which is difficult to implement Password sharing, narrow application

In order to overcome the problem of simple sorting of traditional passwords, small password space, and easy to be peeped and cracked, a multi-combination password with large password space and high difficulty to crack is invented, which is suitable for blind input, can not be peeped, and can realize password sharing recording device and recording method
