    Study Notes

    Digital Ticketing System

    • To reduce load and keep user data secure, the system follows two criteria: minimizing data size in data stores and securely transmitting data.

    Managing Data Size and Security

    • Minimize data size by: • Reducing unnecessary data storage • Compressing data • Storing only essential data
    • Ensure data security by: • Encrypting data during transmission • Using secure protocols for data transfer • Implementing access controls and authentication

    Algorithm for Securing User Password and Verifying Account

    • BEGIN • INPUT username • INPUT password • Hash the password using a secure hashing algorithm • Store the hashed password securely • Verify the account by comparing the input password with the stored hashed password

    Evaluating Security Impacts for Patient Data

    • Two personal data security needs not being met: • Lack of secure log-in system for the computer in the van • Multiple staff accessing the email account without secure authentication

    VPN Feature for Improving Data Security

    • A VPN provides a secure feature by encrypting data transmission between the van's system and the central server, ensuring confidentiality and integrity of patient data.

    Correcting the One-Time Pad Algorithm

    • Errors corrected: • Loop counter should be from 0 to 7, not 0 to 9 • Generate OTP key function should return an array of 8 random numbers • Alphabet array should be used for indexing, not alphabetLocation • Output should be displayed outside the loop

    User Interface for Smart Home System

    • Home screen features: • Lists plugs alphabetically • Annotations describe the function of each element • Schedules allow users to set on/off schedules for individual smart plugs and groups

    Schedules Screen User Interface

    • Schedules screen features: • Multiple on/off times per day • Selecting any day of the week • Function of each element: • Tap text to change plug or group • Press calendar icon to go to Schedules screen • Add a new smart plug • Navigate back to previous screen

    Evaluating User Interface for Accessibility

    • Two additional features recommended to improve accessibility: • Voice control for users with mobility impairments • High contrast mode for users with visual impairments

    Digital Voting System for Student Leadership Positions

    • Programmed components: • Registration and login feature using a universal password and student/staff email address • List of candidates organised by nominated leadership positions • Ability to count votes

    Unprogrammed Processes for Site Administration

    • Unprogrammed processes include: • Distributing universal password to registered users via email on voting day • Importing candidate details and nominations in XML format • Checking/verifying votes • Publishing results

    Candidate Data Structure in XML Format

    • XML structure for "Candidate X": • • `Candidate X` • `Year 11` • `esports captain` •

    Ensuring Implementation of Voting Rules

    • System features to ensure implementation of voting rules: • Unique login credentials for each user • Time-based voting system (8:30 am - 4:00 pm) • Limiting votes to one per user

    Integrating Voting System with School Database

    • Data flow for enforcing voting rules while integrating with school database: • School database provides student and staff profiles • Voting system verifies user credentials and checks for conflicts of interest • Voting system ensures one vote per user and enforces time-based voting rules • Results are published and stored securely
