Requirements of Portable Low-Cost Facial Recognition

The next thing we need to do after the methodologies chapter is Requirements. Since we have selected SDLC, then we can specify the requirements. In this chapter, we will discuss all the requirements for this type of product. 

Gathering & Analysis of Portable Low-Cost Facial Recognition

In order to collect all the requirements of this product, it had to be considered the purpose of the product, which is as face recognition. Since the product is quite unique, the research needs to be conducted along with the similar products / solutions discussed in chapter 2.6. However, since there is no user, then an independent consideration has been made for the requirements by using a mindmap, as presented in the figure below. Along with the entire requirements, this research had to decide if those requirements are quite realistic to be accomplished by an exclusive developer in available time.

Legal Issues of Portable Low-Cost Facial Recognition

Some legal issues were appeared and needed to be addressed since they might leave the product to be vulnerable for any type of legal action. One of the legal issues was in the usage of API. The table below defines a complete comparison of the entire licenses which will be integrated into this software.

Due to there are no exact plans to monetize the product, then there is a concern around some of the licenses that do not permit this. On the other hand, if this will be established as remunerated software, then it will be compulsory to open source the sections which are approved under GPL or else the complete software relying on the mixture of licensed utilized. In case if this open-sourcing of these sections were not perfect, then the replacement needs to be conducted with non-GPL options.

This product also has another legal issue around managing the user data. It is important to make sure that the user’s data must always be protected. For this reason, the user’s data will be saved only inside the Raspberry Pi database. This simply means that only valid users will able to access their own private data. As a consequence, there will be less concern about security since the data will never be saved on any external server. On the other hand, if the data were saved externally, then there must be an implementation of the UK Data Protection Act (Bailey, 2018).

Ethical Issues of Portable Low-Cost Facial Recognition

This project also had some ethical issues to be addressed such as (Floridi & Taddeo, 2016):

Privacy of Portable Low-Cost Facial Recognition

Since the product is around face recognition, then there might be some ethical issues related to the privacy of the users. For this reason, the project needs to implement the legal principles to establish the project.

Security of Portable Low-Cost Facial Recognition

Due to the product will apply the use of Internet connection along with involving a camera, then there is a big concern of security. To tackle this, the project will use a password and firewall to measure security.

Functional Requirements of Portable Low-Cost Facial Recognition

There are various functional requirements included in this project such as:

User Login of Portable Low-Cost Facial Recognition

To secure the users, then there will be a login screen included for extra security. In the future, if the system will be allowed for more than one user, then this individual login will be adjusted with the appropriate settings and personalization to be stored differently for each account of the user.

Image Capturing & Video Recording

This project has the capability to take images or photos and also record some videos taken by the camera. These image capturing and video recording permits as well for the taking of photos or videos from a live stream.

Data Saving

There will be some pieces of data that need to be saved such as details of user login, photos, and also videos. The reason is due to it will be easier for the users to view the data from the previous one once they use the camera.

Usability & Performance of Portable Low-Cost Facial Recognition

Since this product is designed to be used by various users of different stages of age, then it is quite fundamental for this product to be easy and accessible to use by all of the users. For this, the UI systems should be slightly easy to navigate and also the design needs to be flexible, which means that the most used elements must be easy to find instead than hidden behind a massive amount of menu. In addition to this, the portable camera also needs to have a simple learning-arch, with a purpose to make the users enjoy the experience.

Usability is also highly essential since it would provide the users with a further satisfying experience, which will result in making them excited to keep on using the product and also will potentially recommend the product to other people. For this reason, usability is extremely tied up with the product performance. An example of usability can be described such as quick response times. Due to the system software of this product runs on a Raspberry Pi 3, then there is a necessity to optimize the software since there will be only 1GB RAM in this system, and thus, it will not be powerful enough.

Requirements Conclusion of Portable Low-Cost Facial Recognition

The specified requirements which explained and discussed in this chapter are expected to build the future of this product since the Design along with the Implementation should meet all of these requirements. This section discusses the requirements as some important tasks to be achieved in an allocated schedule.
