How BlockSurvey Maintains Privacy & Protects Your Data?
Anonymous AI Usage. You are Anonymous.
BlockSurvey’s AI-powered sentiment analysis prioritizes privacy by avoiding direct data submission to LLM. Instead, sends minimal mapped data to LLM for finding context. This approach ensures anonymity while determining sentiment polarity. Your data is never used for training.
End-to-end encrypted. Own Your Data.
BlockSurvey prioritizes privacy by encrypting all data, ensuring that only the data owner can have access. This privacy-first approach eliminates the risk of unauthorized access, providing complete and secure ownership of data.
Privacy First. No third-party trackers or analytics.
BlockSurvey ensures complete privacy by not running any third-party analytics, meaning no external entities can track or collect your or your audience’s data. This guarantees that all data remains secure and confidential within the platform.
How does it work?
Faster Sentiment Identification
Our AI algorithms rapidly detect sentiment polarity from each of your respondents' data. They also provide the overall collective sentiment of a large dataset received from your respondents.
Rule-based Sentiment Scoring
Every word from your respondent’s data is compared against pre-defined library keywords. This rule-based comparison generates a sentiment score which decides the emotional connotation of the response.
Efficiently Scalable Research
This AI-powered approach can handle vast datasets, including thousands of responses from surveys, making it feasible to identify sentiments of large-scale qualitative datasets efficiently. Additionally, it reduces human bias.
