Method and device for storing secured sent message data

摘要

Methods and devices for storing sent message data are described. The sent message data corresponds to a message sent to a destination by a communication device via a server. The method includes compiling a first portion of the message which has a plurality of components; applying security encoding to the first portion; and storing the first portion. The first portion includes at least one but not all of the plurality of components in the message, and pointers to the components not included in the first portion. A method of verifying sent message data on a communication device is also described.

1. A method of verifying sent message data on a communication device, the method comprising:
compiling a message from a first portion included in said sent message data,
wherein the message includes a plurality of components,wherein the first portion includes at least one but not all of the plurality of components, and includes pointers to the components not included in the first portion, andwherein compiling the message includes
retrieving the components not included in the first portion using the pointers, andcombining the components included in the first portion with the retrieved components to form a compiled message; and verifying the compiled message corresponds to data included in said sent message data, the sent message data corresponding to a secured message sent to a destination by the communication device, wherein one of the plurality of components is a component stored on the communication device and is not included in the first portion, a pointer for the component stored on the communication device is included in the first portion, and the pointer points to a location where the component is stored on the communication device.
