==AFF Enhancement==
+
[[AFF]] is the Advanced Forensics Format, developed by Simson Garfinkel and Basis Technology. The following enhancements would be very useful to the format:
+
* Signing with X.509 or GPG keys data segments and metadata.
+
* Encryption of data segments with an AES-256 key specified by a password
+
* Encryption of the AES-256 key with a public key (and decryption with a corresponding private key)
+
* Evaluation of the AFF data page size. What is the optimal page size for compressed forensic work?
+
* Replacement of the AFF "BADFLAG" approach for indicating bad data with a bitmap.
+
  
The following improvements in the AFF tools would be useful:
+
The technique can assist in demonstrating the co-location (meeting) of individuals, their movements over time, proximity to a scene of crime, and to verify the any defence alibi evidence.
* Modify aimage so that it can take a partial disk image and a disk and just image what's missing.
+
* Improve the data recovery features of aimage.

* A JPEG decompresser that supports restarts and checkpointing for use in high-speed carving. It would also be useful it the JPEG decompressor didn't actually decompress --- all it needs to do is to verify the huffman table.

Flash memory devices such as USB keys implement a [http://www.st.com/stonline/products/literature/an/10122.htm wear leveling algorithm] in hardware so that frequently rewritten blocks are actually written to many different physical blocks. Are there any devices that let you access the raw flash cells underneath the wear leveling chip? Can you get statistics out of the device? Can you access pages that have been mapped out (and still have valid data) but haven't been mapped back yet? Can you use this as a technique for accessing deleted information?

Cell Site Analysis (CSA) is the technical discipline of using mobile telephony signals and network data to triangulate and identify the relative geographic position of a device.

Cell site analysis is considered a highly intrusive surveillance technique and as such normally deployed only in sensitive or serious criminal investigations.

The technique can assist in demonstrating the co-location (meeting) of individuals, their movements over time, proximity to a scene of crime, and to verify the any defence alibi evidence.
