A data channel transmission can be used to authenticate a voice channel transmission. An authentication server can authenticate the identity of one or more parties to a call where at least one of the parties to the call is using a mobile device. A PKI authentication methodology or other symmetric or asymmetric encryption/decryption methodology can be used in a mobile network environment to identify and authenticate a first user to a second user. The authentication request sent to the third party trusted server can be encrypted, signed and transmitted over a data channel (such as an internet connection or SMS or MMS connection), concurrent with the voice channel transmission. In response to validation by the third party trusted server, the third party trusted server can send an authentication indication to the second user's device, which can display identification information and other (optional) data associated with the first user.

A proximity matching system may use broadcast wireless identifiers transmitted by users' devices to match users with other nearby users. The identifiers may be collected by a plurality of agents, then the identifiers may be matched with pre-defined profiles to generate physically proximate users by a remote service. The group of proximate users may be provided to various applications and consumed with summarized properties or individual properties, depending on the approved privacy settings as selected by the users. In some embodiments, the broadcast wireless identifiers may be personal area network identifiers, local area network identifiers, cellular network identifiers, or other broadcast identifier. In some embodiments, the agents may not establish a peer to peer or other connection with the broadcasting device. The agents may be fixed or mobile agents, and the proximity of users may be generated through links between nearby agents in a meshed fashion.
