Privasi data konsumen menjadi isu penting di era digital karena semakin banyak transaksi dilakukan melalui platform online. Penyimpanan data transaksi dalam jumlah besar meningkatkan risiko kebocoran informasi pribadi, baik akibat serangan siber maupun kesalahan pengelolaan data. Artikel ini membahas penggunaan teknik anonimisasi data sebagai upaya perlindungan privasi pada database transaksi, dengan fokus pada metode k-anonymity, l-diversity, dan differential privacy. Penelitian menggunakan metode kajian literatur sistematis dengan menganalisis berbagai sumber ilmiah terkait anonimisasi data dan keamanan privasi digital. Hasil penelitian menunjukkan bahwa setiap teknik memiliki kelebihan dan kekurangan. K-anonymity mampu menyamarkan identitas pengguna, tetapi masih memiliki kelemahan pada data sensitif. L-diversity memberikan perlindungan lebih baik dengan menambah variasi atribut sensitif, sedangkan differential privacy menawarkan perlindungan privasi yang lebih kuat melalui penambahan noise pada data. Penerapan teknik anonimisasi yang didukung regulasi seperti GDPR dan UU PDP Indonesia dapat membantu meningkatkan keamanan data konsumen tanpa mengurangi manfaat data untuk analisis. Penelitian ini diharapkan dapat menjadi referensi bagi pengembang sistem, analis data, dan pembuat kebijakan dalam membangun sistem perlindungan privasi di era digital.
