In one embodiment, a computer-implemented electronic commerce transaction method. The computer receives original image data from a user device, associates a security token with the user, embeds the security token into the original image data to generate modified image data, and provides the modified image data to the user device. To authorize a financial transaction that uses personal data of the user, the computer subsequently receives the modified image data from the user device, extracts the security token from the modified image data, and validates the user and/or the user device. |
