Title: INFORMATION ENCRYPTION METHOD AND DEVICE
Abstract:
Disclosed are an information encryption method and device. A particular embodiment of the method comprises: acquiring customer information, wherein the customer information comprises an item number and a telephone number; selecting a random salt corresponding to the current date from a pre-generated random salt list, wherein the random salt list is used for storing a date and a random salt; using an irreversible encryption algorithm to encrypt the item number and the random salt corresponding to the current date so as to generate a first ciphertext; generating, based on the first ciphertext, a digital second ciphertext; and using the second ciphertext to process the telephone number so as to generate a first encrypted telephone number. This embodiment prevents private customer information from being leaked.
