An
increased level of security occasionally means
that the user's machine will be prevented from
running any Java applets at all, obviously
including ViewONE.
In order to
run ViewONE or ViewONE Pro, users
must be able to run Java applets.
Protection
for those users is afforded by the Applet
Digital Certificate, which is a requirement
of all applets which access the local disks
and which enable printing. Each provider
of certificated applets has had to be vetted
and approved by a certification body -
in Daeja's case, the certification body
is Thawte, a Verisign security company.
As certificated
applets, ViewONE and ViewONE Pro will not
perform any local caching or installation
until the user has accepted the Digital Certificate,
ensuring that the user has the option to
accept or decline.
The ViewONE
and ViewONE Pro Digital Certificates demonstrate
the origin and authenticity of the ViewONE
applets, and are 'signed' by Daeja. The certificates
illustrate that the applets are genuine and
have not been tampered with in any way.
The Daeja Digital
Certificate is clearly marked as being supplied
by Daeja Image Systems Ltd, and whenever
the viewer is first used, new users should
always check that the certificate is still
marked as such (unless Daeja has specifically
provided a license to replace the certificate).
Enabling Java
applets can therefore be accompanied by instructions
on which applet providers' certificates to
accept.
