Problems solved by technology

[0004] However, the currently commonly used serial numbers are generally displayed to customers in plain text in the form of a combination of numbers and letters, and there is no unique correspondence with the computer, which makes it easier to decipher the serial number, and a serial number can be shared between Between multiple computers, the serial number loses its meaning of existence

Embodiment Construction

[0033] Below in conjunction with accompanying drawing and specific embodiment the present invention is described in further detail:

[0034] A software serial number in bitmap format, in the form of a 128×128 pixel color picture, such as figure 1 As shown, the three components of the bitmap pixel discretely and randomly record the authorization information encrypted by the algorithm.

[0035] The method for making a software serial number in bitmap format mainly includes the steps of acquiring information, encrypting and generating a software serial number in bitmap format. The specific steps of the method for making a software serial number in bitmap format will be described in detail below in conjunction with specific embodiments.

[0036] 1) Obtain information: read the hardware verification code string of the client computer, the serial number of the read client hard disk is ST3500418AS, and the serial number of the central processing unit is BFEBFBFF0001067A; input the ti...

Abstract

The invention relates to a bitmap format software serial number. The bitmap format software serial number is a 128*128 pixel color picture, three components of bitmap pixels discretely and randomly record authorization information subjected to algorithm encryption; the authorization information includes hardware checking code character strings and time information character strings, wherein the hardware checking code character strings include hard disc serial numbers and central processing unit serial numbers, and the time information character strings include test duration, serial number generation time, registration time, starting use time, last starting time and last finishing time. The invention also relates to a manufacturing method and a use method of the bitmap format software serial number. The software serial number is shown in an encrypted non-plaintext form, and the the probability that the software serial number is decoded is reduced to a great degree.

Description

technical field [0001] The invention belongs to the technical field of anti-counterfeiting and relates to a software serial number, in particular to a software serial number in bitmap format. Background technique [0002] Protecting intellectual property rights and resisting software piracy are urgent issues facing China's software industry. However, although the country has repeatedly stepped up efforts to crack down on illegal software publications and support genuine software, the actual effect is not ideal. Facing the infringement of the software market by all-pervasive pirated software, software encryption is becoming more and more important. [0003] The serial number is an identification code given by the developer to the software, which is similar to the ID number of a person. Its function is mainly to prevent the software from being stolen by the user. The user must know the serial number to use the software. [0004] However, the currently commonly used serial num...
