This document outlines an IoT application that verifies a visitor's identity and guides them to a meeting using various cloud services. The application flow includes scanning the visitor's ID using OCR, validating their meeting schedule on Google Calendar, using Face++ for face recognition, and providing indoor navigation with Android Maps. Key cloud services discussed are Face++ for face detection, Abbyy SDK for OCR, Google Speech API for text-to-speech, and Google Calendar API for schedule validation.

- 2. AGENDA IoT Background Purpose of our application Application Process flow Cloud Services used Cloud Services Explained
- 3. IoT (Internet of Things) The Internet of Things (IoT) refers to the ever-growing network of physical objects that feature an IP address for internet connectivity, and the communication that occurs between these objects and other Internet- enabled devices and systems.
- 4. Purpose/Idea of Our IoT Application 1. User attends an appointment in a building to meet his host for a meeting. 2. Our standalone application at the host building verifies the visitor’s identity and validates the meeting schedule. 3. Our smart phone application will aid indoor navigation.
- 5. Application Process Flow Scan Visitor’s ID (Optical Character recognition ) User verifies information with voice input Google Speech-to- Text Validate meeting schedule Google Calendar Service. Direct visitor to the meeting room (Bluetooth positioning, Android Maps) Take the visitor’s picture (Face recognition)
- 6. CLOUD SERVICES USED Process flow Phase Cloud Service Used Face Detection and Recognition Face++ OCR Abbyy SDK Calendar Google Calendar API Text-to-Speech, Speech-to- Text Google Speech API Map Android Maps
- 7. FacePlusPlus Free cloud service that offers Face detection, Face analysis and recognition features. Supports cross platforms Fast and accurate functions of face detection from both images and videos. Compares two given images and returns the similarity index
- 8. How it works Input: REST URL Output : JSON Response
- 9. Core Concepts Face++ API has 5 core classes of objects: Image – The input image that is passed via a URL parameter or HTTP POST Face – Face detected within an image.Has unique face_id Person – Face collection of the same person Faceset – Face collection, not necessarily of the same person Group – Set of persons. Used as a search pool to identify a person
- 10. To use Face++ API Sign up at Face++ Developer center Create an application and get the API KEY and API SECRET Download the ‘Faceappsdk’ for the preferred language Include the SDK in the application Access the services through the methods provided.
- 11. Methods Used /detection/detect Detects a face within a given image and returns various attributes of the face. Parameters: API Key API Secret Image
- 12. /recognition/compare Computes the similarity between 2 faces Parameters:Api_key,Api_secret,Face_id1,Face_id2
- 13. Abbyy Cloud OCR Sent as a http POST method along with authentication details, image and the output file name. Eg: http://cloud.ocrsdk.com/processImage?language=English,Russian&profile= DocumentConversion&imageSource=Auto
- 14. Abbyy Cloud OCR Input : Scanned Image of the visitor’s drivers license Output: Text file with the extracted information Methods used: submitImage, processDocument
- 15. Google Text-to-Speech Allows to hear English text spoken by a computerized voice. Generates pronunciations of whatever text is entered the end of this URL: http://translate.google.com/translate_tts?tl=en&q=text Produces a mp3 file with the audio
- 16. Using the service Embed the .mp3 file in HTML’s audio tag <div style="display:none“> <video controls="" autoplay="" name="media"><source src="http://translate.google.com/translate_tts?tl=en&q=Wha t is your name?" type="audio/mpeg"></video> </div>
- 17. Google Calendar API Using client libraries provided by google. Cross-checks the schedule with the host’s calendar. Application name, calendar id and authentication details are to be passed. Uses OAuth authentication protocol. showEvents() method returns the events associated with the calendar.
