CECID Devises a Hassle-Free Way to Breakthrough Email Attachment Size Limitation
 

In view of the increasing need to exchange large files over the Internet and the shortcomings of the current approaches, we have devised a hassle-free way to breakthrough email attachment size limitation. The brand new product, namely Detour, is the first on-premise file exchange server, aiming to address the file size constraint and security concern in sending email attachment.

Very often, when you send email with a large attachment file, delivery failure is resulted due to the small attachment size limitation. Most users resort to inconvenient or insecure alternatives such as FTP or web file delivery service. Detour is an enterprise solution for sending large file securely and at low IT overhead. Taking pressure off email server in sending large attachment, Detour handles attachment delivery of any file size on behalf of the email application in a unified user interface. It has two components: (1) Detour Mail Plug-in, which acts as an agent for email client, handling the attachment delivery request; and (2) Detour Attachment Server, which performs the actual attachment delivery. Users just send and receive files of unlimited size exactly the same way as they used to do with their email applications like Microsoft Outlook and Mozilla Thunderbird through the Detour plug-in.

Apart from allowing you to send email attachment in any sizes without hassle, Detour offers sophisticated monitoring and management of the file transfer process: (1) you can monitor the progress of the file delivery status, (2) control who can read / download the files, (3) regulate the time in which the files are kept in Detour server, and so on. What's more, Detour will handle the file encryption behind-the-scene for you. Hence, your file data is fully protected during the file delivery.

USB Data Protection Application “OneLock” Attracts Massive Attention
 

In recent years, the occurrence of many personal data leakage incidents has caused alarming concern on data security issue. A handy USB storage device can conveniently carry hundreds of gigabytes of information. However, data stored in USB device usually is not well-protected. As a result, we have researched and developed a novel technology – OneLock – a separate keys cryptosystem which strengthens data protection on any off-the-shelf portable storage device like USB flash drive. OneLock is designed to offer a proved, practical and powerful solution to combat data leakage. It protects encrypted data in USB storage beyond a single password. It locks encrypted data in USB storage with a password, as well as confines access to designated computers to improve data security. One of the remarkable merits of OneLock is in the scenario when a USB storage is lost or being stolen, together with the password also being cracked. In such case the data in the lost USB storage still could not be accessed and viewed by unauthorized user without the designated computer.

Since its launch in March 2010, OneLock has aroused public interest on data protection in USB storage. Several interviews have been conducted by newspaper, trade magazine, and radio program. If you missed out on the news, you can view them at http://www.cecid.hku.hk/inthenews.php.

 

 
Project Chameleon Successfully Completed
 

Thanks to ITF funding and industry support, the 1.5-year R&D Project – Universal Web Service Adapter to Facilitate “Software as a Service (SaaS)” Implementation – was successfully completed in Feb 2010.

Coined Chameleon, the project aimed to research and develop a Universal Web Services Adaptor software for rapid development of Web Services interfaces and adaptors for legacy applications to adopt SaaS, a new trend in software development and delivery. With SaaS, software vendors deliver applications to customers as a service on demand, through a subscription or a “pay-as-you-go” model to amortize software costs. A proof-of-concept project was carried out to demonstrate the applicability of the project deliverables.

 

 
The Pilot Project on Large File Transfer Marked Completion of Project Falco
 

We have recently completed the ITF project codenamed Falco which intended to research and develop a multi-site infrastructure that can support secure large file transfer over the Internet with minimal overhead. In this regard, one of the project deliverables, Secure Digital Content Transfer (SDCT) Gateway was developed to provide secure, reliable and transactional transfer of large file over the Internet. The SDCT Gateway has built two very successful real-life use cases.

In Pilot Project 1, SDCT Gateway was deployed to address an aluminum parts and products manufacturer's need of large file transfer to their production factory in China. Pilot Project 2 involved another pilot user, an IT consulting firm. By using existing email clients, transmission of very large file size is not possible because of the file attachment size limit, or it would need the help of alternative channels such as FTP. As a result, we deployed the SDCT Gateway and the plug-in as their file transfer gateway, enabling large size attachment to be sent through email. We have successfully exchanged email with attachment size as large as 4 gigabytes, which approximately equals to the capability of a DVD-Rom. The transmission time for sending out a 4GB file would take roughly two and a half hour only. It demonstrated our project deliverables' effectiveness in handling large file transfer.

 

 
Knowledge Transfer and Market Needs Capture via Consulting Projects
 

Apart from ITF projects, we have engaged in two other consulting projects in the past six months. With ample knowledge and experience in data transformation, we were invited to participate in a project on business data integration for the finance industry. Besides, to tap into the vast mobile application market, we have partnered with other vendors to develop an educational iPhone application as a touchstone.

CECID have built a professional team with a comprehensive portfolio of experience and technical competence. We fulfill deployment demands through consulting services in four major areas, namely, XML Schema Design Service, e-Commerce Architecture Design Service, ebXML and Web Services Infrastructure Implementation Consultancy, and R&D Outsourcing. Customers who are interested in retaining our services are welcomed to email us at info@cecid.hku.hk .
