In-depth and thorough study of the inconveniences caused by the exponential growth of computer technology applied to telecommunications. The author exposes, with great ease and abundance of anecdotes, the current situation in which large companies obtain benefits in the millions by trading with the data of social networks and, on the other hand, unscrupulous hackers use their computer skills to get a hold of the data of bank accounts, copy the content of the servers, break the right to privacy or supplant the identity of their victims. Goodman proves with facts (50 pages of citations) that currently all computer systems, no matter how protected, are vulnerable to cyber attacks. “Future Crimes” will consist of this invasion of privacy, using precisely as "Trojans" the same techniques of control and safeguarding of industrial secrets or economic funds, which reveal the position and customs of those who believe they protect themselves with them. In the final pages, the text offers a series of resources to minimize the risks described. Ideologically, the author's concern about the abuse of information technology by totalitarian governments is clear. As for moral reservations, only the anecdotes that briefly refer to crimes of pedophilia, voyeurism and other types of child harassment.
