Embodiment Construction

[0077] This embodiment is a preferred implementation mode of the present invention, and other principles and basic structures that are the same or similar to this embodiment are within the protection scope of the present invention.

[0078] The present invention is mainly an algorithm for anti-stealing of the Flash content of a bluetooth device, comprising the following steps:

[0079] Step S1, setting a magic word (magicWord), such as "Wlink", in this embodiment, the effect of the magic word is to increase the difficulty of being cracked by people to protect the algorithm;

[0080] Step S2, read the Bluetooth pairing name (DevName) of the current device;

[0081] Step S3, read the Bluetooth address (DevAddr) of the current device;

[0082] Step S4, three character strings of magic word, bluetooth pairing name and bluetooth address are concatenated and merged (that is to say, three character strings are concatenated into one);

[0083] Step S5, according to the character str...

Abstract

The present invention provides an algorithm and system for preventing Flash software content in a Bluetooth device from being stolen, and a storage medium. The algorithm comprises the following stepsof: 1, setting magic characters; 2, reading a Bluetooth pairing name of a current device; 3, reading the Bluetooth address of the current device; 4, combining the three character strings of the magiccharacters, the Bluetooth pairing name and the Bluetooth address; 5, according to the combined character strings in the step S4, calculating a value of md5 to generate a safety code and burn safety codes in a Flash chip; 6, electrifying the Bluetooth device, executing a safety code matching and pairing program, if the safety codes are matched, allowing the system to continuously normally operate,or else, allowing the system to be self-locked; 7, when volume production is performed, employing a volume production tool mptool.exe to burn the software at the device terminal to the flash, and burning the three key parameters to a special position; and 8, when internal test or trail production is performed, employing a trail tool pptool.exe to burn the software at the device terminal to the flash by employing an upper computer.

Description

technical field [0001] The invention discloses an algorithm for preventing theft of software content, in particular to an algorithm, system and storage medium for preventing theft of Flash software content in a bluetooth device, belonging to the field of software technology security protection. Background technique [0002] With the development of the intelligent level of electronic products, many electronic products have built-in software algorithms for intelligent control. For electronic product R&D companies, the biggest problem they face is the problem of software theft. If the results obtained through their own great efforts are embedded in products for application, if they are easily stolen by others, it will bring serious loss. Therefore, it is imminent to study a protection technology mechanism that prevents bad customers from simply reading out and mass production. Contents of the invention [0003] Aiming at the above-mentioned shortcoming that software in elec...
