Abstract
The claimed subject matter relates to an architecture or arrangement that can limit access to sensitive information by means of encryption. In particular, data obtained from a payment instrument at, e.g., a Point-Of-Sale (POS) location can be encrypted at an early stage such that a POS (or another) application does not have access to the data in an unencrypted form and/or does not have access to a means for decrypting the data. For example, a Public Key Infrastructure (PKI) arrangement can be employed such that a back-end payment processor can define encryption algorithms, associate itself with a public key, and maintain a private key for decryption. The public key can be delivered to the POS location and employed for data encryption, and, moreover, the PKI can be regulated by the more trusted parties.
