SafeShopper client

Client: SafeShopper

Task: SafeShopper is an application to view the Gluten allergy information of food products by scanning their EAN-13 barcode. The decoded barcode is passed to a web service that determines whether the product is safe or not safe.

Solution:
Develop an application that retrieves food product information by EAN 13 (EPC) barcode. The client runs on mobile phones and decodes the barcodes using the video mode. The user scans the barcode for a few seconds while the image is extracted and decodes the EAN-13 barcode. Product information is retrieved via web request to the central SafeShopper database and compared to the profile of the user. The application has a customized user-friendly GUI and the product information screen adjusts automatically to fit the information to the device screen.

OBS (Object Based Services) client

Client: www.mobiubiq.org

Task:
To provide a system that allows users to scan barcodes and provide access to object-based services, i.e. perform actions with the recognized object, such as viewing information, opening a website, blogging, saving the barcode as a bookmark, etc.

Solution:
Develop an application that enables services based on the recognized QR barcodes and EAN 13 (EPC) barcodes on the phone.

The client runs on mobile phones and decodes barcodes. The camera runs in video mode to extract the image to decode either a QR barcode or an EAN-13 barcode when available.

The user need only point at the barcode and wait until it is recognized; upon recognition a request is sent to the service directory with the string of the decoded barcode. The service directory returns data for the object and a list of relevant services.
The application has a customized, user-friendly GUI.

EAN-13 and QR barcodes decoding software

Client: www.mobiubiq.org

Task:
Develop a Symbian OS C++ application that decodes a QR barcode and EAN 13 (EPC) barcode and passes the decoded data to the J2ME application responsible for data processing on the Nokia platform.

Solution:
The system consists of two programs running on Nokia N95 and N96; one is a Symbian OS C++, and the other is J2ME midlet.

  • The C++ application works with the camera of the mobile phone and responsible for barcodes decoding.
  • The J2ME application communicates with C++ application via sockets.

The J2ME application commands the C++ application to decode a barcode: the user does not take a picture, since the camera runs in video mode and is constantly extracting an image as it decodes a QR barcode or an EAN-13 barcode from the extracted image. Once the barcode is decoded (or an error occurs), the C++ application sends the result back to the J2ME and goes to background until the next command.

PiSafe Desk - secure information

Description: Develop a secure data transmission and storage system for computers or computers and mobile phones.

The system uses two-dimensional bar codes to deliver the security keys and a combination of encryption and authentication/authorization for user verification. Compression methods are used to optimize the amount of data stored and transmitted. A specially developed protocol for package header descriptions enables post-processing of information received on mobile phones.

Functionality:
The application allows the user to do the following actions:

  • Capture and decode 2D barcodes in manual or continuous modes;
  • Setup capture modes and image sizes;
  • Save captured images to the phone;
  • Process the captured information from the barcode and present it to the user as follows:
  • Manually enter safeuri ‘access’ key to obtain data to be processed from the server.
