“…We can easily verify that N(u, v) ≥ 2 for any u, v OE &, therefore, & is 1-EC/AUED. Describing efficient constructions as well as encoding and decoding algorithms of t-EC/AUED codes is beyond the scope of this paper, so, again, we refer the reader to [2], [5], [6], [7].…”

“…To write the weights, we needed 13 numbers, therefore, 4 bits. These 4 bits can be encoded into a 1-EC/AUED code of length 11 as described in [6]. As in Example 2.1, assume that the following (1, 7) sequence of length 32 has been written:…”

“…In Algorithm 3.1, vector u has to be encoded into a 4-EC/AUED code. Following the methods in [7] or [6], u can be encoded into a 4-EC/AUED code of length 38. Using the (1, 5) systematic modulation code of rate 1/2, we obtain a tail t of length 76.…”

Abstract-We present coding methods for protecting against tampering of write-once optical disks, which turns them into a secure digital medium for applications where critical information must be stored in a way that prevents or allows detection of an attempt at falsification. Our method involves adding a small amount of redundancy to a modulated sector of data. This extra redundancy is not used for normal operation, but can be used for determining, say, as a testimony in court, that a disk has not been tampered with.
