RescueMe Overview Percussive Protocol RescueMe Phone Implementation Platforms and Versions RescueMe Tablet Implementation Database Security Concerns Challenges Presentation Checklist

Problem: When trapped after an earthquake there is no cell service.

RescueMe App: the Solution Solution: To change those random noises into a message, like a complex morse code.

RescueMe: How does it save your life? Allow victim to send critical information to rescuer, for example:  location  condition  number of people This is called the Percussive Protocol

How Protocol Works: Sending Encoding Pulses (will be 2, 3, 4, or 5) After the user inputs the message, the system encodes it using the Percussive Protocol. The message is now a series of pulses ranging from 2- 5.

How Protocol Works: Receiving Rescue workers are using Tablet to rescue Decoding algorithm input pulses Display message Repeat for multiple inputs The rescuer, using a seismometer or audio sensor, listens for these pulses. Then inputs them into the Tablet. As the pulses are entered the message is decoded using the Percussive Protocol.

How Protocol Encodes: "A Message" "A" " " "M" "e" "s" "s" "a" "g" "e" "A" ASCII / UNICODE / etc values Base 2 # Base 2# Apply Error correction Base 2# Base 4# 2001 If Selected: Base 4# add 2 to each Digit to get Pulse values 4223

How Protocol Decodes: " " 3,2,2,2,6,6,3,4,5,2,3,4,3,4,6,6 Grabs the first part 3,2,2,2 and Decodes Grabs the Subject partNo subject in this message Grabs the Content part 3,4,5,2,3,4,3,4 and Decodes Decoding: -2 to each pulse convert to base 2# undo error correction if necessary convert to ACSII or Unicode

RescueMe Phone: Home Send a message to rescue workers Practice receiving messages from victims Settings o Prestored messages o Sending speeds o Number of rest pulses Learn about the application

RescueMe Phone: Settings Save / Delete prestored messages Three different speed levels Five different rest pulse lengths

RescueMe Phone: Send Message No error correction Error correction with Golay and Hamming Simple message with error correction

RescueMe Phone: Compose Message Can send different types of each message

RescueMe Phone: Sending Message The victim will transmit these pulses by using a rock or some other item. Strike to send pulse Take a rest

RescueMe Phone: Receive Message Display the textual message Display the pulse sequence Buttons to input pulse Can fix the pulse input if there was an error.

Platform and Version Relationship

RescueMe: Tablet Implementation Message Entry Message Display Rescue Information Message Central Rescuer Information Tablet Information

Rescue Central Database Concept

MUST: Message content Pulse Bursts Entered Time Pulse Burst Entered Date message received Start of message time GPS Longitude GPS Latitude Trappers location Description Option: Picture attached Voice note attached Drawing attached

Rescue Central Database Concept Further Concern: Multi-language database save space vs. convert languages

Future Security Concerns: Future iterations of this application will have the greatest security concerns.

Future Implementation Diagram: Concern 1: Concern 2: Authentication/ Concern 3: Concern 4:

Security/Privacy Concerns: Percussive Protocol Jamming Malicious entities intentionally sending percussive signals to flood the tablet receiver

Security/Privacy Concerns: Database Information Flooding Flood the database with false reports to snag it o similar to a DOS or DDOS attack Forge reports in order to direct rescue teams in certain directions o Message legitimacy

Security/Privacy Concerns: User Authentication Public key crypto o (Asymmetric) Private key crypto o (Symmetric)

Challenges Faced in Development Learning Android development platform Integrating prototypes into the Android System GUI made in JAVA Percussive Protocol Error correction algorithms Multi-language in database
