is a good example of Crisp's design, development and security
expertise. It involved mobile application development on Android and
Windows NFC phones, RFID and QR tag programming and the creation of
a back-end security server solution.
m-Commerce solutions focus on individual services, or how users pay
for services, so they miss out on a vital preliminary step; the
secure discovery of trusted services. Users of all capabilities need
to easily find the services that are relevant to their needs in a
way that they can trust. TagBuddy allows tags (RFID or QR codes) to
be placed on objects and to be securely accessed via a mobile phone,
providing trusted information and service discovery that is context,
location, language, user and device aware. The deployed solution
consists of tags attached to objects, an application downloaded to
the user's smart phone and a back-end server.
tag/mobile solutions have been shown to be vulnerable to
modification, misuse and fraud; misdirecting users to adult and
gambling sites, to criminal premium rate services, or to fake
phishing sites. Even in cases where there is no direct financial or
safety risk, there is potential for brand damage, compromised
privacy and loss of customer confidence. However, TagBuddy has an
effective security solution based on the tags, phone and
back-office, which is transparent to the user. Recent project work

Improving the dynamic service selection algorithm.
Trials with Transport for London (TfL) and the Royal Holloway (RHUL)
Picture Gallery, to get user feedback
on usage (including multi-lingual, audio/visual) and performance.
Adding support for another mobile OS/platform (Win8).
