A method for enhanced validation of cryptograms for varying account number lengths includes: storing one or more primary account numbers and a plurality of formatting templates, each template being associated with an account number length; receiving a selection indicating a specific primary account number; identifying a specific formatting template where the associated account number length corresponds to a length of the specific primary account number; receiving an unpredictable number from a point of sale device; generating a cryptogram based on at least the unpredictable number and one or more algorithms; generating a data string, wherein the data string includes at least the generated cryptogram, the specific primary account number, and the unpredictable number, and wherein the data string is formatted based on the identified specific formatting template; and electronically transmitting the generated data string to the point of sale device.

Method and system for enhanced validation of cryptograms in cloud-based systems

The present invention relates to a method and system for synchronizing a personal identification number (PIN) value stored in a mobile computing device, with a PIN value stored on a remote server. The remote server receives a request from the mobile computing device to record a PIN value, the request comprising the PIN value. The PIN value is recovered from the received request and stored at the remote server. An instruction set arranged to record the PIN value in a secure hardware element comprised within the mobile computing device is generated and transmitted to the mobile computing device. The instruction set executes on the mobile computing device in order to record the PIN value on the secure hardware element.
