The probiotic value is therefore found in the framework data. However, from the frame data alone, a reasonable person would not necessarily be able to know whether the frame data they are viewing is the same as the one that prevailed when the file was created. For this purpose, it will be necessary to seek the assistance of a skilled person with the knowledge and ability to examine whether a change has been made in the framework data. However, for this purpose, he may be required (and therefore also the parties and the court) to have access to the copy of the evidence (as opposed to the copy).
Alternatively, if there is a certified source, that is, a copy whose authenticity is unquestionable and from which the copy was created, the reliability of which is being examined, and its "hash value" comparison with that of the copy under examination will allow us to know if the information is different."
Later on, Vaki examines the possibility of preserving copies in a digital archive, and after such a review, he turns to examine the difficulty where it is a digital document that is not preserved in the manner described or in another manner that provides an approved source. Regarding these cases, it was written: "The source of the difficulty lies in the fact that where two documents are presented to the court - one 'original' and the other that has been altered, the court will not always be able to know what the original is and what the forgery is... Whatever the case, the information contained in the frame data that accompanies a digital copy and which is absent from a physical print or even a digital copy may be of great importance to the issue that is clarified in the trial. In many cases, it is possible - whether with or without the assistance of an expert - to draw many different conclusions from him that could not have been foreseen in advance. For these reasons, I am of the opinion that where it is evidence of digital origin, it should be determined that a copy of the file must be submitted to the court on digital media - as opposed to a copy or physical printout of the information. This is subject to the exceptions recognized in case law to the rule regarding the best and most appropriate evidence in terms of their nature to the umbrella of digital evidence.
