11.6.2 Mobile Phone Hosting Personal Information
This second scenario is related to what was proposed in the mobile databases
section. Figure 11.9 shows a mobile phone hosting personal information such as a
curriculum vitae or a personal photo album and granting access to that data to social
networks such as LinkedIn (where we would like to share our more actual CV) or
Flickr (where we would like to share our pictures with our friends and relatives).
Users should introduce their phone number in the social networks, which would
send a petition to the phone in order to be granted access to specific contents. If
access to a certain social network or to a certain content is not granted, the website
is not able to retrieve the data and share with other users of that social network.
11.7 Conclusions
In this chapter, we have reviewed the current and future roles of mobile phones in
community-built databases. Although most of the observations could be applied to
other mobile devices such as portable game consoles or e-readers, we have focused
the paper on mobile phones due to their huge industry, their market penetration,
and their strong links with users that have made possible important changes in our
cultures, and have a great impact on everyday activities.
The success of community-built databases can be attributed to the rise of the
Internet and broadband connectivity. However, there are more users worldwide
utilizing mobile phones than users connected to the Internet, and in the next years
the number of users accessing the Internet from mobile devices will surpass the
number of users accessing Internet from desktop or notebook computers. That
