The computer receives customer registration information and encryption parameters from a customer, then transmits them to the server of an entity such as a pharmacy or bank. After the entity utilizes the transmitted encryption parameters to encrypt confidential portions of a message to the customer, the computer captures the message by way of receiving, photographing, scanning, or otherwise obtaining a copy of the message. The computer identifies glyphs in the message indicative of the corresponding encryption parameters as well as where the encrypted portions of the message start/end. Using the identified glyphs and corresponding encryption parameters, the computer decrypts the confidential portions of the message and displays the message in entirety on the computer.
