(Personally I think your question is the limit to be considered or not, a cueston IT Security.
your question is rather general and can bring in deception, it is unclear whether you are talking about email or mail, the book is well known, and speaks only of "mail" address.)
So I'll assume you are talking about traditional mail.
A security expert, both in computer science and in other environments, it's really a good observer, when using computers to solve the questions of security, or if used for research, should be obtained multiple information and should be used half provisions in the country where you live, because the IT development level is not the same in any country in the world.
Is not the same research a U.S. address and to investigate an address in a country elsewhere in the world less developed (I avoid names undeveloped countries to avoid any type of discrimination).
Therefore we can say that there is no tool or overall methodology to identify this type of services.
Before all, let's assume you want to use clear public and legal methods to obtain information and you do not is developing or attempting to use any tools of government to access this private data and reserved for other citizens.
The first major question must always be:
My research activity is legal?
If you sense that your business needs to help identify fraud, and does not have Access to research facilities, may choose to hire legitimate services that will do the service for you. In many countries there are state entities and parastatals, to help you get this type of information.
If you identify that your research is legal and will only use the information available on the net legally. You should proceed to make some deductions.
Suppose you want to investigate a U.S. address. and that there is no real difference between a
ghost address and a
private legitimate address
It will be almost impossible to know if this address is associated with a real person or entities. especially if this entity is not a
But should you think that those who use these services legally just want to hide your real address, and does not care to hide if using some service to hide your own address.
So easily may found right useful information through automated search engines.
Well one of the weak points of this type of service (mail drop) is that you can not generate fictitious buildings and that would not come profitable to the company that offers this service, build a fictional building, for each customer.
So this is going to generate a common denominator. It is likely that other users on the web, are using the same personal address so we can carry out three simple cross-searching.
So if we can find some other user on the web is using this address. for it deserves support from any search engine. This first search will be useful for next searches. as a method of comparing different cross data of the residents.
A second search can be performed on a search engine for finding people and residents as this example:
You can find information about nearby residents and to the entered address.
Every business, especially services company, needs visibility to get new customers, and if the company is not big enough, is likely to have the same commercial office address their service address, doing a search on the building you can find readily useful data about the building and its residents.
With these simple tools, you can create your detection pattern,
as you can see, all this information could be obtained automatically by scanning software and the data could be analyzed with a simple neural network trained pair this type of work. empowers well be implemented in any type of web service.
The address used in the three searches is completely random and has been used for demonstration purposes only.
