This research was conducted to find out what steps the government has taken in striving for society to be 'digital literate', what obstacles are faced and what digital forms have been implemented by MSME players and cooperatives that have gone digital. The method used is an integrative review. The results of this study found that the government has tried various ways to make SMEs and cooperatives more “digitally literate”, from infrastructure, training to collaborating with related institutions and companies that have gone online first in terms of systems of operational (transaction), marketing and also payment. Obstacles to infrastructure and available facilities as well as the lack of information and human resource skills in utilizing digital are challenges faced by the government, SMEs and cooperatives. Therefore, better coordination from up to bottom is needed so that understanding and utilization of digital can be distributed evenly. For MSMEs and cooperatives that have “go digital”, found that they are still at the basic and intermediate levels, while the platforms used are still in the sharing economy, e-commerce, social media, cloud computing and other digital platforms related to applications to simplify transactions and operations.

E-commerce contributes to the improvement of communications between the company, producers, distributors and customers. However, it should be noted that success in e-commerce depends upon determining effective factors in e-commerce. There is a set of effective inside organisational and outside organizational factors in e-commerce which should be taken into consideration during the development of e-commerce. According to the recent results of DESI Index, Latvia lags behind the EU average on integration of digital technology by businesses. Despite excellent connectivity and good digital public services, Latvian SMEs do not use effectively online selling, social media, cloud computing and big data possibilities. At the same time, it is recognised nationally that e-commerce provides good opportunities to develop business, including in the regions. Taking into account the before-mentioned, the aim of the paper is to analyse the factors contribution to the development of e-commerce in the regions in Latvia. Main results of the research: in general, factor groups “Technological development” and “Social factors (human skills)” were assessed the highest among Latvian entrepreneurs. Such individual factors as desire to develop, employee knowledge, and managerial attitude, technological development in the world, and managerial knowledge and existence of financial resources in the company were evaluated the highest in terms of effect on usage of e-commerce in the business. In case of regional cross-cut, in Kurzeme, Riga and Latgale regions entrepreneurs are rather in favour of technological development factors affecting the usage of e-commerce, while entrepreneurs in Zemgale and Vidzeme regions think that social factors affect the development of e-commerce the most.

Indexing and semantic code in news draw on a base of well-defined vocabulary from classification systems used by news editors for search tags, but journalism also uses leaked data, mobile metadata logs, and datasets for visualisations. The tagging systems in news, like NewsCode, are embedded in CMS and help to bind data for cross-referencing purposes. The defined concepts have an ontological base that relate to “news” and they are structured in hierarchical and logical ways. For many years social media tags were unstructured, but folksonomy approaches do not exclude semantic methods, and vice versa. Media cloud tools can also be used by journalists to generate lightly interactive graphic visualisations or to integrate data onto maps. However, data and metadata should also be used to develop new semantic systems to better protect journalists in conflict zones and to embed the values and ethics of journalism into algorithms for journalism training systems.

With the development of cloud computing, more and more video services are moving to the cloud. How to realize fine-grained access control of those data on cloud becomes an urgent problem. Attribute-based encryption provides a solution. However, heavy computation is still a bottleneck restricting the wider application of attribute-based encryption in cloud computing. In addition, we find that expression of the access control structure on media cloud can be further improved. To solve these problems, we propose an enhanced media ciphertext-policy attribute-based encryption algorithm and introduce its two key components, the multiple access tree and the key chain. To increase the scalability of the proposed algorithm, we discussed the issues of multi-authorization, user revocation, and 1 − n multiple access tree. Security analysis shows that enhanced media ciphertext-policy attribute-based encryption can successfully resist chosen-plaintext attacks under the decisional bilinear Diffie–Hellman assumption. Performance analysis proves both theoretically and practically that the proposed algorithm incurs less computational cost than the traditional ciphertext-policy attribute-based encryption, multi-message ciphertext-policy attribute-based encryption, and scalable ciphertext-policy attribute-based encryption by optimizing the access control structure. Our proposed algorithm has strong practical significance in media cloud.

Now a days data is growing at a very fast rate. Here data is referred not only with organizational data but the data also from non-organizational and social media, the data may be PDF’s, Photos, Audios, Videos, XML file etc. To earn more profit, the organizations tends to establish Cloud Storage with minimum establishment cost and high security. To provide robust and secure platform is the main aspect of cloud. Lots of algorithms have been designed and implementing for securing the data at cloud but the attack on 2014 on cloud in which 50 million accounts were hacked, shows that cloud is not fully secured. The main focus of this paper is to draw attention towards security issues and cost-efficient cloud and the solution for implementing it.
