  • Publication number: 20150326554
    Abstract: A social network (SNET) is divided into one or more circles having different trust levels. Communications between the different SNET circles is bridged by an SNET device capable of communicating with devices associated with the different SNET circles, even if those devices cannot communicate directly with each other. When a communication is sent between SNET circles, the SNET device verifies the trust level associated with the communication, and bridges the communication based, at least in part, on that trust level. The SNET device can be located in a demilitarized zone associated with both the first SNET circle and the second SNET circle. Where different SNET circles use different security secrets for communications between members, the SNET device can store different keys for each of those circles in separate, restricted portions of memory.

  • Patent number: 9100453
    Abstract: A social network (SNET) is divided into one or more circles employing separate security secrets, e.g. keys, for communication between members. A device can be a member of more than one circle, and store different keys for each of those circles in separate, restricted portions of memory. When a member leaves a circle, new keys can be generated and distributed to the remaining members. Before and after joining a circle, a level of trust associated with the device or human member can be determined based on third party trust verification and a trust history. A requirement for multiple current circle members to vouch for the prospective member can be imposed as a condition of membership. Each circle can be assigned different trust and access levels, and authorization to receive information can be checked before transmitting information between circles.

  • Publication number: 20150154405
    Abstract: Members of a social network (SNET) circle can share content with other members of SNET circle, members of the same SNET that are not members of the same circle, or send content to people or devices outside of SNET. Trust chain can be used alone or in conjunction with other security measures to assign or select an appropriate level of content protection and SNET access. A trust rating or level associated with a trusted human member can be conferred to a social network device, allowing that device to be included in the trust chain. Trust can also be conferred from a trusted social network device to a child device of the social network device. A trust processing module can work in cooperation with one or more trust authorities to establish initial and updated overall trust levels of a human or device associated with the SNET.

  • Patent number: 8966643
    Abstract: Members of a social network (SNET) circle can share content with other members of SNET circle, members of the same SNET that are not members of the same circle, or send content to people or devices outside of SNET. Different levels of content security can be applied to the shared content, depending on who requests the content, the destination of the content, user preferences, content type, SNET, SNET circle, or other security parameters. Content can be tagged to limit the number of times it can be accessed, the length of time access is allowed, and to otherwise control redistribution. Content can also be protected by limiting host network access to the content, implementing SNET circle firewalls and virtual private networks, or transcoding content before allowing transmission to non-SNET circle or SNET members. Docking of devices into an SNET security circle can be restricted to properly secured devices.
