Information security and privacy : 7th Australasian conference, ACISP 2002, Melbourne, Australia, July 03-05, 2002 : proceedings

The Seventh Australasian Conference In Information Security And Privacy (acisp) Was Held In Melbourne, 3–5july, 2002. The Conference Was Sponsored By Deakin University And Icore, Alberta, Canada And The Australian Com- Ter Society. The Aims Of The Annual Acisp Conferences Have Been To Bring Together People Working In Di?erent Areas Of Computer, Communication, And Information Security From Universities, Industry, And Government Institutions. The Conferences Give The Participants The Opportunity To Discuss The Latest Developments In The Rapidly Growing Area Of Information Security And Privacy. The Reviewing Process Took Six Weeks And We Heartily Thank All The M- Bers Of The Program Committee And The External Referees For The Many Hours Of Valuable Time Given To The Conference. The Program Committee Accepted 36 Papers From The 94 Submitted. From Those Papers Accepted 10 Papers Were From Australia, 5each From Korea And Usa, 4 Each From Singapore And Germany, 2 From Japan, And 1 Each From The Netherlands, Uk, Spain, Bulgaria, And India. The Authors Of Every Paper, Whether Accepted Or Not, Made A Valued Contribution To The Conference. In Addition To The Contributed Papers, We Were Delighted To Have Presen- Tions From The Victorian Privacy Commissioner, Paul Chadwick, And Eminent Researchers Professor Hugh Williams, Calgary, Canada, Professor Bimal Roy, Isi, Kolkota, India (whose Invited Talk Was Formally Referred And Accepted By The Program Committee), And Dr Hank Wolfe From Otago, New Zealand.
