Methods and systems for anonymous digital identification are disclosed and may include detecting the presence of a first communication device associated with a first set of content that is distinguishable from an identifier associated with the first communication device, detecting the presence of a second communication device associated with a second set of content that is distinguishable from an identifier associated with the second communication device, and in response to a determination that the devices are geographically proximate to one another, providing matched content to at least one of the first and second devices. The matched content may be based at least in part on the first set of content, the second set of content, and a shared or complementary interest associated with the first and second devices. The interest may have been previously expressed by a user of the first or second devices.
