We wanted to know how to improve the design and/or functions in Chat-Secure, regarding the security-problem. People should immediatly see that it's a secure chat through its interface. So we searched for possible symbols that provide security and tried out some designs to improve the current look of the chat.
We interwiewed ten people of these courses of studies below. Since we all studies something similar we had an easy access to them. We asked them about their chat behavior in general and especially how they think about security.

How we analysed the data: We searched for specific answers in the interviews and looked how it could help to spot a problem. Then we put all our results together and created an affinity diagramm.
We chose them, because they are part of our social environment. We thought about what would be important for ourselves to develop the questions. Since we`re in the security-group we tried to focus especially on that topic.
Yes, they do, but it doesn`t bother them.
What we learned from our user research: We got a lot of information about the requirements and the possible use of a chat application. The most important features people wanted to be part of such an application where group chat functionality, image transfer, smileys and an easy to use but appealing interface. People often want to plan parties in a chat, so the group function could be necessary and image transfer is also an important factor of communication for most people.
It was also interesting for us to find out that the main percentage of the users know about possible security issues:
However, they did not try to find an alternative. Related to this we also found out that people using chat software for business had much more concerns about their personal information and especially the topic and content of the talk then the private users.
Since insecurity in their currently chats doesn`t bother them much, they just haven`t thought about a secure alternative yet. Most important thing has always been, that all friends use the app/chat. They would change to a secure chat, where all friends are logged in, though.
The interface should communicate security to the user. Therefore we want to improve the interface of ChatSecure in a way, that everyone is able to understand what is meant with the symbols. To create such a design, we drew some of our own design-ideas on a paper. It showed the message window and some applications and icons we added to it, e.g. the lock symbol next to the Accountname and in the speech bubbles itself. These things intensify the security-feeling. Then we discussed those ideas, made a prototype and tested it on a comrade who wasn`t in our working group.
The ideas of last week worked quite well, but not properly understandable. The problem of the red color we`d chosen for the Send-Button for an insecure message didn't work out. Our test subject thought the button couldn't be clicked at all. So, in the next week, we would look for similiar applications and how they deal with authentification and security methaphors. After that, we would improve our prototype with the results of the last weeks and try out different approaches to solve our problems, regarding the prototype itself, the layout and the colours. Then we would test it again.
