Weekly project updates



I have almost finish my project build and I used a 36 images in my project which will be shown to the user, this makes my system similar to the password system in the way of login and the number of characters since the numbers of the English characters is 36 and also the images will appears to the user as a group and the later will make his/her choice from them as the case with passwords in which the user can pickup a number of password letters from the given list.

the following is my first experiment


Experiment 1
The main aim of this experiment is to shades the light on the security level of the system regarding the educated attack; this will contain involving a group of couples user to take part in the experiment and use the system and then make each of the couples to guess the other images to identify weather it is possible to guess the other part images by knowing what he likes or what his test of image and to what ration the guess is correct and meaningful, also it’s interested to identify on which the image selection was based on for example some user may select images on the character they like or colors or something like that and other might make the selection based on personal preferences and during this experiment the users will be asked to specify what their selection was based on and also to see if some of these issue are more predictable than others which is useful when designing the systems in future since some of the highly predictable subjects might be neglected or removed from the images and so on.
Other important issue will be discussed during this experiment is the pass images and how easy the user can explain his pass images to someone who haven’t seen them before, in this part the users will be asked to describe their images and write information about the image number and description and also the user ID, this information will be used by someone else to login to the others account and then the successful logins ratio will be calculated.
This first part of the experiment will involve four to five groups of couples some of them are a male of females friends that was together from a long time which means that each of them knows enough about what the other like and dislike, the other are a boyfriend and girlfriend which are in relation from longtime or they might got married which also means that they knows enough about each others.

The main procedure of the first part of this experiment:
This part will be related to the groups of couples only and it involves the following:

1- Each one of the couple will be asked to register to the system and when finishing this step he will be asked to do the authentication then the other part should try to authenticate with the use of the partner used name to see if the later can guess what are the pass images of the partner or not?
2- The second part will involve asking each of the partners about what the images selection was based on trying to get some information about that the asking the other partner about what the images guessing was based on to see what are the main issues that are usually been focused by someone who trying to guess someone else’s images which will be useful for the designers in the futures.



The second part of the experiment will involve all the surveyors who take part with the survey and this part will have the following.

1- Each of the users will be asked to leave a brief description about his images such as the number of the used images and description about each image,
2- The above information with related to the user name will be used by other user or by the system developer to see if it’s possible to login using these information and if yes to what level the logins are successful or what are the successful log in rates,
3- Then each of the users will also been asked about the image selection and what it was based on to clarify what are the main issues that the images selection will be based on.
Hi, Mr. Chi, if you have any note about this experiment please support me and it will be very kind of you


This form is to be filled by all the students during experiment 1
1- Name:
2- User name:
3- Number of pass images:
4- Images description:

The above information will be collected from each student after finishing the registration stage and it will be used later by the system developer to find out how easy to tell the pass images to someone else who haven’t seen them before and the login results will be recorded for each student as successful or not successful.
1-the result:


This form is to be filled by each partner of the couples during experiment 1

1- Name:
2- user name:
3- number of pass images:

The above information is recorded for the partner after the registration and it will be used by the other partner to try to login by guessing the pass images of the former.
The following questions are required to be answered by the partners to be used later during the data analysis by the system developer.
The first partner (the registered partner):
1- the images selection was based on what ( what you was thinking about when you make your selection)
2- what of the following image properties make you decided to select the image ( the colors of the image, the main subject inside the image, the images remind you by something you like, you have seen this image before)

The second partner (the guessing partner)
1- your guessing for partner’s pass images was based on what (your partner will select images based on what from your point of view)
2- what do you think that your partners selection will be based on from the following ( ( the colors of the image, the main subject inside the image, the images remind you by something you like, you have seen this image before)

EXPERIMENT2

this experiment need to be lunched before the respondents finishing their authentication before a week period of time and it aims to shades the light on some critical issues regarding the system and collect information and data from the respondents about the system and how it acts from their perspectives and these issues and the questions that will be answered are shown below:

1.1.1 The system speed and weather it consumes a lot of time

• Which of the following processes takes more time from you (selecting the pass images during the registration, thinking about a new easy to remember password)
• Arrange the following process in term of its time consumption, the most time consumption is the first one and so on (view the images, focusing on specific images, make the selection).
• The decision of how many pass images will usually take longer time than choosing the images themselves (agree, neutral, disagree, don’t know)
• Which of the following decisions takes more time from you during the registration (deciding the number of pass images to be used, deciding which of the given images will be your pass images)
• Arrange the following entities in descending order in term of which one could takes more time to be done (login to the picture base system with the pass image, login using a user name and password, login to the ATM machine using a bank card and pin number)

1.1.2 The system usability

• The assistance during the registration and the login process is required for which of the following reason more than the others (to know what is the required information in the registration means, to know how many images need to be used, to feel more relax from the possibility of making mistake and ask for advises, didn’t need any assistance during the hole registration and authentication process)
• What of the following reason confused you when choosing your pass images during the authentication (there was no enough images that you like in the image set, the different subjects of the images makes it difficult to decide, there was similarity between images)

1.1.3 The ease of use in term of the users memorizing ability

• What of the following makes you confused when choosing your pass images during the authentication (there was images similar to your pass images, there was similar colors between the images, you completely forget you images, there was no confusion when choosing the images during the authentication)
• Arrange the following entities in descending order in term of which one could be easily and quickly forgotten ( pass images in the picture based system, a group of faces in the pass face recognition system, passwords, pins)
• How many password application you have and how many passwords you are using for them all?
• Arrange the following actions according to how did you start identifying your pass images (focusing to a specific location from the challenge set, identifying the main color of the pass image, identify the main object in the image).
• When you select your images at the first log in what of the following sentence is near to your feeling (I have almost forget my images and couldn’t remember them, I have weakly remember them but still need to be trained on them, I remembered my images well and pick them up easily)


both experiment 1 and experiment 2 are finished now and the above questions have been used for both of them

the following question have been used during the first experiment to identify some of the reasons that makes the respondents select their images and also to collect information about how the respondents have described their images and show some of the issues that make the description easier or more difficult from the respondents point of view.

the questions:

first of all the respondents have been asked to describe their pass image, each image should be described individually and this description will be used later by someone else to log in using the description and the user name and the result will be recorded.
the description will also be useful to make the answer of the question easier to the respondents because there will be question relater to the description process.

1. the images selection was based on what (what you was thinking about when you make your selection):

2. Your images selection was based on which of the following?

You like the character that is in the image
Personal preferences like color or light
None of the above and the selection have been made randomly

3. What of the following image properties make you decided to select the image?

The colors of the image
The main subject of the image
The image reminds you by something
You have seen this image before

4. What of the following image properties you prefer to describe more than the others to indicate your pass images ?

The main subject of the images
The main color of the images
The lightness and darkness

5. Which of the following situation easier from your point of view?

describe an image that located among images similar to it
describe an image among a group of images that defer from it

6. when you describe your pass images, which of the following sentences is near to your thoughts?
the description of an image still the same with any group of images it might displays with and doesn't depend on the other images
the description depends on the other images to show just the difference for the described image



the below questions have been used during experiment 2 which aims to shade the light on the usability, time consumption, and the efficiency of the system in term of memorable ability of the respondents, further to these issues one more question have been added at the end of them to shade the light on the respondents behavior regarding using the passwords authentication systems and show approximately the number of similar passwords that might been used by the respondents




1. Did you log in successfully?
Yes
No

2. Which of the following processes takes more time from you during the registration?


3. Arrange the following processes in term of its time consumption, the most time consumption is the first one and so on




4. Which of the following decisions takes more time from you during the registration?


5. Arrange the following entities according to which one could take more time to be done the more time consumption is the first


6. The assistance during the registration and the login process is required for which of the following reason more than the others


7. What of the following confused you more when choosing your pass images during the registration?


8. What of the following makes you confused when choosing your pass images during the authentication?



9. Arrange the following entities in descending order in term of which one could be easily and quickly forgotten, the easier to be forgotten is the first




10. Which of the following helps you when selecting your pass images during the authentication?


11. When you select your images at the first login what of the following sentences is near to your thoughts
