A secure storage device with the identical external dimensions, form factor and hardware connectivity configuration of a standard removable storage device, for securing digital data such as digital images from digital cameras at the acquisition stage. Original digital camera data is saved in the memory of the secure storage device after performing one or more security functions, including encryption, creation of an authentication file, adding data to the image data such as fingerprinting, and adding secure annotations such as separate data included in an image header. These processes are transparent to a host device receiving secure data from the storage device because standard protocol is used to write to the secure storage device. The device prepares original authentication data from original digital camera data, and encrypts and stores both the original authentication data and the original image data. The use of the device includes reading the original image data on a separate computer, by means of direct downloading of the data and or mounting the removable storage device on the computer. The computer is able to read data on the raw transfer level as if the device is a standard unsecured storage device. On the content level, the data remains secure. The computer can be programmed with software whereby the encrypted original authentication data can be decrypted by a user having a password key. Additional software may enable the computer to verify the authentication data of the image data for questionable authenticity. The secure storage device secures data from any computerized device that stores data on a removable storage device, such as a portable computer.
