An approach is provided for reducing communication traffic/cost and protecting content. A criterion application causes, at least in part, reception at a first recipient one or more first data encrypted with one or more first recipient criteria as a public key of identity-based encryption, the first data including one or more first instructions. The criterion application matches one or more second recipient criteria corresponding to the first recipient against the first recipient criteria that encrypted the first data. The criterion application decrypts with a first decryption key one or more of the first data corresponding to at least a matched one of the first recipient criteria, when one or more of the second recipient criteria match the at least one of the first recipient criteria. The criterion application executes automatically or on demand at the first recipient one or more of the first instructions included in decrypted first data. |
