The rapid growth of cross-platform applications has significantly increased the volume and diversity of sensitive user data processed across heterogeneous and distributed environments. Personally identifiable information, device identifiers, behavioral data, and financial information are routinely collected to support personalization, analytics, and service optimization. While these practices enhance application functionality and user experience, they also introduce substantial privacy risks, including unauthorized data access, device fingerprint–based re-identification, cross-user data leakage, and large-scale data breaches. These risks are further amplified by distributed processing architectures and extensive third-party library integrations commonly used in modern cross-platform systems. This study aims to systematically analyze privacy issues in cross-platform applications by examining the types of sensitive data involved, identifying dominant privacy threats, and reviewing state-of-the-art privacy-preserving mitigation strategies. A systematic literature-based methodology was employed, focusing on recent Scopus-indexed journal articles, conference papers, and book chapters. The analysis synthesizes findings using thematic categorization and a conceptual research framework that maps sensitive data sources to privacy threats and corresponding mitigation mechanisms. The results indicate that privacy risks in cross-platform applications originate not only from external attacks but also from internal architectural weaknesses, such as flawed authorization logic and excessive data sharing across system components. Privacy-preserving techniques including differential privacy, federated learning, blockchain-based data governance, secure multi-party computation, and fine-grained access control mechanisms are shown to provide stronger privacy guarantees compared to conventional centralized approaches. However, these techniques also present trade-offs related to system complexity and performance. Overall, the study highlights the importance of adopting a multi-layered, privacy-by-design approach to ensure sustainable, trustworthy, and regulation-compliant cross-platform application development.

The integration of Artificial Intelligence (AI) chatbots into customer service operations within digital banks has become a transformative trend in the banking sector, particularly in Indonesia.

The integration of AI in customer service operations holds significant potential for digital banks and the broader financial sector to improve operational efficiency, reduce costs, and meet the evolving expectations of customers.

In the current era of modernization, almost everyone uses the internet to help solve their problems. Including security activities. Currently, many companies provide security services. There are also many companies or individuals who are or want to look for companies providing security services but they don't know where to look for these companies because of the lack of information. Therefore, to make it easier for security service seekers and security service providers, a design is needed that can be a solution to the problems of both parties. It is hoped that the required design will meet the needs because it must go through several stages of testing in accordance with standards and the needs of potential users. UI/UX analysis and design involved 10 respondents from two actors, namely companies providing security services and companies or individuals seeking security services. The final design was tested by the same 10 respondents with four types of testing. Testing is carried out repeatedly until respondents feel that the design meets the needs of potential users.

Technology develops from time to time influenced by human activities and needs that continue to increase as well. Technological developments also play a role in helping the agricultural sector.
