BODY COUPLED COMMUNIICATION SYSTEM
First Claim
1. A body coupled communication system for providing secure communication, the body coupled communication system comprising:
- a first device comprising a first body coupled communication interface for forming a body communication network via a body transmission channel along a body of a user when the first body coupled communication interface is in a vicinity of the user;
a second device comprising a second body coupled communication interface for forming the body communication network with the first device via the body transmission channel when the second body coupled communication interface is in the vicinity of the user, the first body coupled communication interface and the second body coupled communication interface are configured to transmit information between each other via the body transmission channel, wherein the vicinity is a maximum distance at which the first device and the second device are capable of transmitting and/or receiving the information via the body transmission channel, wherein the body coupled communication system is configured to provide security to the user to prevent misuse of the first device or the second device, wherein the security is provided by;
the first device being configured to detect whether the second device is present in the body communication network, andthe first device being configured to alarm the user when the second device is no longer present in the body communication network based on the detecting.

Abstract
A body communication system (100) is provided which comprises a first device (110) and a second device (130). The first device (110) comprises a first body coupled communication interface (114) for forming a body communication network (170) via a body transmission channel (160) following a body of a user (150) when the first body coupled communication interface (114) is in a direct vicinity of the body of the user (150). The second device (130) comprises a second body coupled communication interface (134) for forming the body communication network (170) with the first device (110) via the body transmission channel (160) when the second body coupled communication interface (134) is in the direct vicinity of the user (150). The first and second body coupled communication interfaces (114, 134) communicate information with each other via the body transmission channel (160). The body coupled communication system (100) is configured to provide additional security to the user (150) of the body coupled communication system (100) to prevent misuse of the first device (110) or the second device (130).
