Electronic device and method for authenticating software based on blockchain

An electronic device comprising:

• at least one processor;
• and
• a storage device coupled to the at least one processor and storing instructions for execution by the at least one processor to cause the at least one processor to:
• obtain a first identification code and a first hash value of a first software;
• generate a first authentication code by performing an encryption operation on the first identification code and the first hash value;
• write the first identification code, the first hash value, and the first authentication code into a blockchain as authentication information of the first software;
• obtain a second identification code of a second software to be authenticated and calculate a second hash value of the second software;
• determine whether the second hash value of the second software is the same as the first hash value;
• generate, in response that the second hash value of the second software is determined to be the same as the first hash value, a second authentication code by performing the encryption operation on the second identification code and the second hash value;
• determine whether the second authentication code is the same as the first authentication code;
• and
• determine, in response that the second authentication code is determined to be the same as the first authentication code, that the second software is copyrighted.
