Secure Interactions with Large Language Models in Financial Services : A Study on Implementing Safeguards for Large Language Models

Fredrikson, Gustav January 2024 (has links)
This thesis examines the use of Large Language Models (LLMs) in the financial sector, highlighting the risks and necessary safety measures for their application in financial services. As these models become more common in various financial tools, they bring both new opportunities and significant challenges, such as potential errors in financial advice and privacy issues. This work introduces a detailed safeguarded framework designed to improve the reliability, security, and ethical use of LLMs in financial applications. The framework includes specific safety features like checking user inputs, detecting incorrect information, and preventing security breaches to tackle these challenges effectively. Using quantitative testing benchmarks and case studies with a financial chatbot, this thesis shows that this framework helps reduce operational risks and increases trust among users. The results show that while LLMs already have some built-in safety features, adding tailored security measures greatly strengthens these systems against complex threats. This study advances the discussion on AI safety in financial settings and provides a practical guide for implementing strong safety measures that ensure reliable and ethical financial services.

Drivna män, dynamiska kvinnor? : Kontaktstrategier och könsassociationer i Nordnets platsannonser / Driven men, dynamic women? : Relationship building strategies and gender associations in Nordnet's job postings

Strandvall, Malin January 2013 (has links)
Studiens primära syfte är att undersöka hur målgruppen potentiellt framtida kvinnliga arbetssökande upplever det språkliga tilltalet i nätbanken Nordnets platsannonser. Hypotesen att det språkliga tilltalet i Nordnets platsannonser bär spår av manliga drag och attraherar män i högre utsträckning än kvinnor är en central utgångspunkt för undersökningen som görs. Ett sekundärt syfte med studien är även att ur språkvetenskapligt perspektiv undersöka hur de relationsskapande strategierna ser ut i fem slumpmässigt utvalda platsannonser från Nordnet. Studien utgår från frågeställningar som berör attityder till det språkliga tilltalet och hur platsannonsernas relationsskapande strategier associeras med manligt eller kvinnligt språk. Frågeställningarna besvaras med hjälp av två kvantitativa metoder: en enkätundersökning samt en textanalys, vars resultat legat till grund för enkätundersökningens utformning. 39 respondenter deltog i enkätundersökningen, varav 22 kvinnor och en kontrollgrupp på 17 män. Till grund för textanalysen låg fem slumpmässigt utvalda platsannonser från Nordnet. Studien har en sociolingvistisk ansats och bygger vidare på Gaucher, Friesen & Kays (2011) forskning om effekterna av könsbundna ord i platsannonser samt Xiaoli Fus (2012) forskning om platsannonsens kontaktskapande strategier. Resultaten från textanalyserna visar att de kontaktskapande strategierna i Nordnets platsannonser stämmer väl överens med tidigare forskning samt att användningen av olika attitydmarkörer och läsarinkluderande pronomen har en gynnsam effekt på målgruppen. Vidare talar resultaten för hypotesens förkastande - åtminstone vad gäller den undersökta gruppen - då merparten av de undersökta kvinnorna uppger sig vara lockade att söka en tjänst hos Nordnet och även upplever platsannonsens kontaktskapande strategier på ett positivt sätt. Inte heller uppgav de kvinnliga respondenterna att de associerade det språkliga tilltalet med manligt språk; tvärtom skattade männen i kontrollgruppen valda delar av platsannonsens språkliga tilltal som mera maskulint än kvinnorna. / The objective of this study is to investigate how a specific target group; potential, future female applicants, perceive the language in Nordnet’s job postings. The hypothesis that the language used in Nordnet’s job postings attracts men to a greater extent than women is a central starting point for the investigation. A secondary objective for the study is also to examine how the interactional metadiscourse, e.g. relationship building strategies, look like in five randomly selected job postings from Nordnet. The study is based on questions that apply to attitudes towards linguistic traits in the job postings and how the relationship building strategies is associated with masculinity or femininity. These questions are answered by two quantitative methods : a survey and a text analysis, the results of which formed the basis of the questionnaire survey design. 39 respondents participated in the survey, including 22 women and a control group of 17 men. The basis for text analysis were five randomly selected job postings from Nordnet. The study has a sociolinguistic approach and builds on Gaucher, Friesen & Kay's (2012) research on the effects of gendered wording in job postings and Xiaoli Fu's (2011) research on interactional metadiscourse in job postings. The results from the text analysis shows that the relationship building strategies of Nordnet’s job postings are consistent with previous research and the use of different attitude markers and reader-inclusive pronouns has a beneficial effect on the target audience. Furthermore, the results speak for hypothesis rejection - at least for the group studied – since most of the female participants claimed to be attracted to apply for a position within Nordnet and also experienced the job posting’s strategies in a positive way. Neither did the female participants associate the language with masculinity; on the contrary, instead the male participants rated selected parts of the job postings interactional metadiscourse as more masculine than the women did.
