Spam, biometrics and a blog

Purpose - The purpose of this paper is to review developments on the internet, especially those of general cybernetic interest. Design/methodology/approach - The ever-present problem of spam, or unsolicited e-mail, is reviewed with reference to its discussion in a particular web site, one of a useful series. A new means of automatic personal identification by face recognition is described. A valuable "blog" (web-log or open online diary), with information and discussion of mainly software topics, is introduced. Software allowing manipulation of the PC registry is discussed, with the observation that it is unfortunate that registry operation is opaque to users. Findings - The paper finds that spam is with us in increasing volume. Automatic face recognition has been achieved. The opacity of an important part of the PC operating system is partially remedied by available software. Practical implications - Some anti-spam measures are reviewed. Face recognition as a means of identification has a number of advantages including operation without intrusive gadgetry such as fingerprint sensors. The opacity of operation of a PC registry is regrettable but is partially remedied by availability of certain software. Originality/value - It is hoped this is a valuable periodic review.
