Abstract: A method of securely transmitting a message from a sending entity to a receiving entity via a network. A Processing String Engine is communicatively coupled to the sending and receiving entities. The sending entity requests the Processing String Engine to provide a network routing path for message transmission from the sending entity to the receiving entity and to provide a processing string for the message transmission. The Processing String Engine identifies a network path and generates a processing string. The sending entity appends the processing string to the message and sends the message to the receiving entity. The message is unreadable while the processing string is appended thereto. Upon receipt of the message with the appended processing string, the receiving entity requests removal the processing string. Upon successful verification of the receiving entity, the processing string is removed, and the message is returned to the receiving entity.

Abstract: A method of privatizing mobile communications using a dynamic International Mobile Subscriber Identity (IMSI) and Mobile Station International Subscriber Director Number (MSISDN). A first privacy token having an associated IMSI and MSISDN is provided to a User Equipment (UE). The first privacy token has a predefined validity period. The IMSI and MSISDN assigned to the privacy token are shared with a plurality of Mobile Network Operators (MNOs), while the International Mobile Equipment Identity (IMEI) of the UE remains concealed. A communications session for the UE can be established based on the first privacy token during the validity period thereof. Upon expiration of the validity period, the first privacy token and the associated IMSI and MSISDN are released to the token database, and their association with one another is deleted. The UE is then provided with a second privacy token having a different associated IMSI and MSISDN.
