1. A method for authenticating a unit of digital data of a mobile communications device, comprising;
- capturing said unit of digital data with a mobile communications device;
generating authentication data to confirm at least one of the source or integrity of said unit of digital data;
capturing biometric data identifying a person who captured said unit of digital data;
appending said biometric data to said unit of digital data to provide reference data corresponding to said unit of digital data, wherein said reference data further includes data selected from the group consisting of;
data representing the date and time said unit of digital data was captured;
data representing the location said unit of digital data was captured;
data identifying the owner of said mobile communications device;
data identifying said mobile communications device;
data identifying a network operator of a mobile communications network to which said mobile communications device is connectable; and
data representing the position or distance of an object within a visually captured scene relative to the mobile communications device or relative to another object within said visually captured scene; and
capturing at least two images of a visually captured scene from different viewpoints and determining information about the position or distance of at least one object within said scene relative to said mobile communications device or relative to another object within said scene and including said information in said reference data.
