Method and apparatus for security mechanism for proximity-based access requests

An approach is provided for providing security mechanism for proximity-based interactions among devices. A first device (e.g., a memory tag) may determine a request for interaction between the first device and a second device (e.g., a mobile phone), wherein at least the first device is associated with at least one first antenna and at least one second antenna. The first device may determine a first signal received by the at least one first antenna and a second signal received by the at least one second antenna. Further, the first device may determine one or more differences in one or more characteristics of the first signal and the second signal. Furthermore, the first device may process or facilitate a processing of the one or more differences to determine whether to allow the interaction.
