Patent ID: 8533266

Claim:
A method comprising: receiving, by at least one computing device, a first group of indications associated with a first group of modalities and a second group of indications associated with a second group of modalities, wherein the first group of indications is associated with a first remote computing device and the second group of indications is associated with a second remote computing device, and wherein the first and second groups of modalities are usable to determine whether a first user associated with the first remote computing device is within a physical presence of a second user associated with the second remote computing device; determining, by the at least one computing device, a confidence value for at least one modality of the first or second groups of modalities based at least in part on an indication associated with the at least one modality, the indication being from the first or second group of indications, wherein the confidence value indicates a likelihood that the first user associated with the first remote computing device is within a physical presence of the second user associated with the second remote computing device; and upon determining that the confidence value is greater than a boundary value, performing, by the at least one computing device, an operation to indicate that the first user associated with the first remote computing device is within the physical presence of the second user associated with the second remote computing device.
