QBefore writing the question nothing is illegal ... I am in Saudi Arabia so let me to be concerned about the laws and regulations ..... Again there is no harm to anyone and nothing illegal (if you care so much I could explain in private )
Now let me focus on issue: There is a very simple looking system we are going to deal with , There is a a switch and few terminals ( actually by terminals I mean few end points that user can put a smart cart and do some shopping , this card include the customer id and the time of purchase and amount of purchase ) attached to it , all these terminals ( endpoints are attached to a system having a Linux OS . All the information of all people doing the shopping are going to be sent to this system and probably stored on hard drive ( I am not sure or it might be stored somewhere else , you need to figure it out ) . This system is connect to a database , all these info will be sent to a database ( there is a intranet network) and there , they Will find the number of customer and amount they purchased.
Surprisingly this system can operate offline , which means if I cut off the connection all the info will be stored locally and when I connect it to the network the info will be transferred to database.
What I want to do is to find out where the data are stored and how can I change it (data stored on my system could be secured somehow). I can provide you with all you need info on the hard drive and whatever you need ...
