Two-dimensional code information hiding method based on run-length coding
A technology of two-dimensional code information and run-length encoding, which is applied to secure communication devices, record carriers used by machines, and key distribution, can solve the problem that binary images or text information cannot be hidden, and does not involve encoding methods and two-dimensional code structures. , does not involve the encryption and decryption of encrypted information, and achieves the effects of high security, good information concealment, and high compression resistance

[0052] see Figure 1-6 1. A two-dimension code information hiding method based on run-length coding, which is characterized in that carrier information carrier and secret information secret are input; first, the run-length coding method is used to input the carrier information carrier into the key generation process and generate a key Key ;Through the encryption algorithm, the secret information to be encrypted is embedded in the carrier information carrier to obtain the encrypted text EncryptText, and then the encrypted text EncryptText generates a two-dimensional code image QR; the sender sends the above two-dimensional code image QR to the receiving party; the receiving party After receiving the above-mentioned two-dimensional code image QR, decrypt it through a decryption algorithm to obtain the carrier information carrier and secret information secret.
