During the preparation of a subject known websites can make you great service. In order to use the best, the ideal is to have a bounce logic. The principle locate on their results pages related information or discrete options out some information to use in a Google search or via another service, multiple transactions based on collected data, etc.
Without assume that you definitely will validate the information received, you will have a body of evidence that will allow you to have everything a handy context in the case of an investigation or interview.

These services are not revolutionary but their use in a journey full of trails open investigation, as we shall try to show below.

The example of logic rebound used here aims to clear brush Internet activities of Laurent Tapie, son of Bernard.

Whois, or how to find contacts who purchases a domain name like bernardtapie.com
When you buy a domain name, you fill the contact fields: first name, name, email address, phone. By default these fields are accessible to all, and there are very few buyers who believe in making their data inaccessible. To search the database, you use what is called whois.

Official websites like internic.net or afnic.fr do not give useful results. The one I recommend is who.is. Apart from advertisements and other video without interest, it compiles all of the most interesting data.

During your research first – on bernardtapie.com in this case – you will not find nothing very interesting: as the official engines who.is gives little information on the first page. But clicking on the small “History” tab you will find recent changes owners.

ICANN is working on a radical change of the system of Whois databases, to gather information on domain names in a centralized database, which access would be possible only with prior authorization.

The WHOIS database that gathers information on domain names and their owners could disappear. Computer World reports indeed a working group of ICANN, the Expert Working Group on gTLD Directory Services (EWG) released a report (.pdf) recommendation to drastically change the operation of the service.

Currently, each domain name registry provides its own research Whois server, which is publicly accessible without authentication. But due to extensive standardization, records do not provide all the same data, or not in the same form, it is not always easy to know what Whois query server, and especially there is a very patchy compliance the privacy of the owners of domains. Some services offer to mask the identity of the administrative and technical contacts of the domain, but not all.

The EWG proposes a system revolution. Rather than having a multitude of self Whois services, the ICANN working group proposes to set up an aggregate register, centralized, called Aggregated Registration Directory Service (ARDS). Various technical proposals are made to ensure the basic update, but especially the issue of privacy and the fight against spam (via the Whois data of mass aggregation) is central.

If the proposal is implemented, it will seek authorization prior to access information of a domain name, which would profoundly change the philosophy of Whois, and transparency offered so far. Once the certification granted, the use that will be made will be observed, to rule out those who abuse their access rights to the database.
