Unless expressly included in this Agreement, all communications and other communications in this agreement (a) are personally forwarded to the following part, b) by certified mail with a return bulletin requested in a secure sealed envelope; (c) by night mail with proof of delivery by an internationally recognized delivery service, (d) by confirmed fascicie or (e) by electronic communication. Messages sent by hand, certified mail or overnight, are considered to have been received. Fax communications are deemed to have been sent during the shipment (except that if they are not provided to the recipient during normal business hours, they are presumed to have been given to the recipient when the business opened the following business day). Electronic communications are deemed to be received when the sender has received confirmation from the intended recipient (for example. B by the “requested acknowledgement” function, if available, e-mail or other written confirmation). Biometric measurements of this type are useless as passwords because they cannot be changed when compromised. [Citation required] They could be served, however, except that they have been so easily deceived so far that they may have little certainty that the person who signed a document was in fact the person who did it. For example, a reproduction of the electronic signal generated and transmitted to the computer system responsible for placing a signature on a document can be recorded by interception techniques. [Citation required] In the case of fingerprints, a Japanese professor and a few PhD students managed to fool all the fingerprint readers of the business they had with a little candy angels and a little ingenuity.  In the case of a user`s image, Vietnamese researchers successfully demonstrated, in late 2017, how a specially designed mask could beat Apple`s Face ID program on the iPhone X.  The next part, which influences the legal status of a signed document, is the content of the document and the intent of the parties.
What was signed? Do the parties intend to sign the document and make a legal commitment? These signatures are extensive electronic signatures, but they must meet certain EU standards (for example. B on the basis of a “qualified certificate”), which means that they provide additional protection checks against advanced counterparties. You create this signature using a device specially designed to create electronic signatures. As a general rule, a court must recognize the same legal value as the handwritten signature of these certificates. With all this information, sales teams with an electronic signature solution can speed up the final process for each sale and resolve any questions potential customers have about the legality of contracts signed electronically. The legal value of an electronic signature depends on the person who applied it, the identity of that person and the fact that the signed data did not change after the signing. Electronic signatures can be created with increasing certainty, each with its own requirements and means of creation at different levels demonstrating the validity of the signature. In order to offer an even stronger proof value than the advanced electronic signature described above, some countries, such as the European Union or Switzerland, have introduced qualified electronic signatures. It is difficult to question the authorship of a signed declaration with a qualified electronic signature – the declaration is not too reticent.  From a technical point of view, a qualified electronic signature is implemented by an advanced electronic signature using a digital certificate encrypted by a security signature building device and authenticated by a qualified trusted service provider.  i See Lothar Determann, eSignature Laws Need Upgrades (papers.ssrn.com/sol3/papers.cfm?a
