The word' signature' seems to be signed in the court handbook. Therefore, it is uncertain whether the court will include electronic authentication as a "signature" in order to solve this uncertainty through legislation. The High Court of Australia accepted the fax signature in the case of Electronic Leasing Company Limited v. Anderson (197 1). This area is not completely clear. In the case of Molodyski v. Weimar Australia Limited (1980), the question is whether the document signed by fax reaches the signed document to be sent (at the offeror), and then the receiving country (the offeror) signs a binding agreement. Cohen's J (attached) pointed out that the validity of the signed documents provided by fax depends on the original signed agreement delivered. If the fax signature you intend to sign is used to verify the document and is regarded as a personal signature, the document is regarded as an official signature.

In the case of pastoral area Weiman United Co., Ltd. v. Anborn Co., Ltd. Yang J, a fax did not meet the requirements of both parties in writing and signing, and it was a promise, not a judgment. On the contrary, these two decisions were put forward in the case of New Mexico Retirement Co., Ltd. v. Baker et al. (J of Cohen in 1989). The fax signature is not the original signature, so there may not be enough places to sign. In, the question does not need to be decided because there is no signature.

In EDI system, signature or other authentication can be done in many aspects, for example,

1.by uses a secret numeric code, similar to the PIN code used by ATM;

2. By using the public key encryption technology of a more complex system, it provides a mathematical scheme for arranging computer data;

3. Digital signature used in Utah Digital Signature Act 1996 (see 3.4); or

4. Use specific computer software, such as "pen operation"

The question is whether these electronic signature technologies are suitable for electronic bills of lading, which is beyond the limited scope of this paper. However, one thing is that these methods may technically verify the source of the mail, but they may not meet the legal requirements of signature.

The Model Law clearly gives appropriate technical solutions the same legal effect as traditional signatures, and allows the parties to agree on specific means. Article 6 of the Model Law provides that:
