Question

Without the reassurance of a handwritten ink signature, there is no obvious way to verify the authorship.

Alternatively, imagine that a bank receives an e-mail from a client, which instructs that all the client's funds should be transferred to a private numbered bank account in the Cayman Islands. Once again, without a handwritten signature, how does the bank know that the e-mail is really from the client? The e-mail could have been written by a criminal attempting to divert the money to his own Cayman Islands bank account. In order to develop trust on the Internet, it is essential that there is some form of reliable digital signature.

Write three to five sentences evaluating the author’s argument. In your response, identify and evaluate the claim and whether the evidence supports the reason and the claim.

Answer 1

These should be from a country unconcerned about its offshore citizens and what they do outside its borders. There must also be no tax or military requirement for non-residents. Passports must be available to foreigners. Dual or multiple nationality is one of the cornerstones of the PT philosophy. The PT should strive to have several passports regardless of original nationality. A second passport always comes in handy and has often saved the skin of many an individual during times of war, persecution and political upheaval.

Answer 2

The reason that protecting our information is important is so that people can be sure about who really sent them information. The evidence is a hypothetical situation about how a criminal could steal money by pretending to be someone else if encryption wasn't possible. The reason and evidence logically support the claim because they show one way that the Information Age would not be successful – people could easily steal money – if information is not protected.
