Data may be encrypted using a public key. From a plurality of functions executable on the data, one or more functions may be selected. The selected one or more functions may be associated with the encrypted data. The selected one or more functions may provide exclusive access to the data. A data structure specifying conditions for access to the one or more functions may be created. An exclusive interface to provide access to the one or more functions may be created. The interface, upon determining that one or more conditions from the conditions are satisfied, may grant access to the one or more functions. The encrypted data, the associated one or more functions, the data structure, and the interface may be included into an object.
