2.  The next wave of technology, promising a step change in results, is Social
media, Mobile, Analytics, and Cloud – all combined into the acronym
SMAC.
 Social networks and Mobility are rapidly transforming our relationships
with people and data.
 Analytics have driven customer intimacy to previously impossible levels.
 The cloud has irrevocably changed the way we store and share
information.

3.  There are over 1.39 billion monthly active Facebook users which is a 13
percent increase year over year.
 42% of marketers report that Facebook is critical or important to their
business to promote their content and products
 As of Feb 2015, LinkedIn has 347 million registered members across 200
countries.
 By 2016, it is estimated that there will be around 2.13 billion social
network users around the globe, up from 1.4 billion in 2012.

4.  42% of mobile phones in the US are smartphones. In Europe, the figure is
44%.
 More than 87% of phone owners access the Internet or email on their
handheld device.

5.  A study from IBM and Oxford University's School of Business reveals
almost two-thirds (63%) of UK and Ireland businesses recognize the
competitive advantage associated with Big Data.
 Online retailers such as Amazon have realized increased revenues
implementing Big Data.

6.  74% of enterprises are using some form of cloud services.
 In the last few years, cloud computing has grown from being a promising
business concept to one of the fastest growing segments of the IT
industry.
 Now, recession-hit companies are increasingly realizing that simply by
tapping into the cloud they can gain fast access to best-of-breed business
applications or drastically boost their infrastructure resources, all at
negligible cost

7.  As more and more information on individuals and companies is placed in
the cloud, concerns are beginning to grow about just how safe an
environment it is.
 The current data security in cloud is employing single/multiple
encryptions via public and private key.
 Existing solutions is using single way encryption and decryption
techniques - NOT DYNAMIC.

8.  Solution - The data will be encrypted and stored in the cloud and it
will be again dynamically encrypted with timestamp.
 Retrieval - First the dynamically encrypted data is decrypted by
cloud vendor (By AES algorithm) and the actual decryption is done
by end user (By RSA algorithm).
 SCUDE : Storage in Cloud Using Dynamic Encryption.

9.  We implemented the SCUDE with DropBox as a cloud service.
DB –
Stores dynamically generated key
Server –
Encrypt and decrypt data using AES
Internet
Client -
One time encryption and
decryption is done using RSA
File Transfer
File Transfer

10.  The primary advantage is preventing hacking and cracking of data from
unauthorized source.
 Reliability and scalability can be improved.
 This algorithm provides high security with firewalls.
 Data breach and data loss is the major drawback in the existing system
which has been overcome in SCUDE – Our Solution.

11.  Today's SMAC technologies provide a robust and extensible architecture
for the long-term growth of network solutions.
 The flexibility, cost effectiveness, and transformative nature of SMAC
offers a solid platform for potential growth and innovation
 With our SCUDE, This next generation technology platform will be more
secure and reliable.
