Abstract: Encryption operations using private and public cryptographic signature keys may be used to facilitate secure and uniquely identifiable audit records relating to website content classification. Blockchain may be used to facilitate collection, storage, and sharing of encrypted audit records. Based on shared encrypted information (e.g. from the blockchain or elsewhere) a content evaluation consensus may be formed. Collections of encrypted audit records may be processed and results of the processing may also be shared via the blockchain. Subsequent operations can include sharing of the processing results.

Abstract: Embodiments described herein disclose a mobile device system and method for determining suggested payment sources within an application executed by the mobile device. A location of the device may be detected. A merchant corresponding to the detected location may be identified, and characteristics of the merchant may be received. Additionally, non-public promotions offered by an entity associated with a stored payment source or with the merchant are received. Based on the payment sources, characteristics, and promotions, a suggested payment source for a transaction between the merchant and a user of the mobile device is determined and displayed on a touch-sensitive display. The suggested payment source may be selected by the user. Thus, the user is presented with a suggested payment source based on the merchant, and may maximize reward account points, cash back, or minimize interest, based on the suggestion of a payment source.
