In order for anyone being able to do some sort of research, one needs to have six digits of the controlnumber.Dakkus wrote:Hmm.. Telling the first five numbers should - in my understanding - not cause any security threat, as the rest five (plus one) of the numbers would still be obscured, resulting to tens of thousands of serial numbers to go through in order to get a hit with a serial number seen in the note listing.
They would also serve all the same functions the current scheme (Axxxx1234xxx) has.
In other words, changing the number showing system from Axxxx1234xxx to A12345xxxxxx would apparently not pose any kind of a threat of fake hits.
Right?
Reason: Some countries use these six digits to define the sheet position. Example Portugal: 50 Euro (De la Rue printing H) uses both, five and six digits.
D1 is M91285xxxxx* as well as M913075xxxx*.
But as you fear security threats (something, I still do not go along with) you may forget the whole thing anyway.
How do you want to check the Dutch notes, where they use digits no. 5, 6 and 7 (J.Enschede G printig) to define the sheet position.Oops I forgot, for 100 and 200 Euro, they even use digits nos. 5, 6, 7 and 8 !!!!
As far as I can see, the best way is the way, Eurotracer shows the numbers, i.e. A12345678xx* .
On the other hand, someone who wants to cheat can easily define full sheets and lodge the numbers. Just in case, do you want a full range of numbers for Finnish F.C.Oberthur 5 Euro notes ? Easy as pie ! By the way, here you need the first six digits as well.
By the way, how does EBT check the correctness of given numbers ? How does EBT check the sheet position. Is a Greek 20 Euro Y00026016112 N001C4 or is it N001G5 ??
